Structural and functional studies of Bacillus stearothermophilus serine hydroxymethyltransferase: the role of Asn(341), Tyr(60) and Phe(351) in tetrahydrofolate binding

SHMT (serine hydoxymethyltransferase), a type I pyridoxal 5'-phosphate-dependent enzyme, catalyses the conversion of L-serine and THF (tetrahydrofolate) into glycine and 5,10-methylene THE SHMT also catalyses several THF-independent side reactions such as cleavage of P-hydroxy amino acids, trans-amination, racemization and decarboxylation. In the present study, the residues Asn(341), Tyr(60) and Phe(351), which are likely to influence THF binding, were mutated to alanine, alanine and glycine respectively, to elucidate the role of these residues in THF-dependent and -independent reactions catalysed by SHMT. The N341A and Y60A bsSHMT (Bacillus stearothermophilus SHMT) mutants were inactive for the THF-dependent activity, while the mutations had no effect on THF-independent activity. However, mutation of Phe(351) to glycine did not have any effect oil either of the activities. The crystal structures of the glycine binary complexes of the mutants showed that N341A bsSHMT forms an external aldimine as in bsSHMT, whereas Y60A and F351G bsSHMTs exist as a Mixture of internal/external aldimine and gem-diamine forms. Crystal structures of all of the three Mutants obtained in the presence of L-allo-threonine were similar to the respective glycine binary complexes. The structure of the ternary complex of F351G bsSHMT with glycine and FTHF (5-formyl THF) showed that the monoglutamate side chain of FTHF is ordered in both the subunits of the asymmetric unit, unlike in the wild-type bsSHMT. The present studies demonstrate that the residues Asn(341) and Tyr(60) are pivotal for the binding of THF/FTHF, whereas Phe(351) is responsible for the asymmetric binding of FTHF in the two subunits of the dimer.

Hot deformation characteristics of INCONEL alloy MA 754 and development of a processing map

The characteristics of hot deformation of INCONEL alloy MA 754 have been studied processing maps obtained on the basis of flow stress data generated in compression in the temperature range 700-degrees-C to 1150-degrees-C and strain rate range 0.001 to 100 s-1. The map exhibited three domains. (1) A domain of dynamic recovery occurs in the temperature range 800-degrees-C to 1075-degrees-C and strain rate range 0.02 to 2 s-1, with a peak efficiency of 18 pct occurring at 950-degrees-C and 0.1 s-1. Transmission electron microscope (TEM) micrographs revealed stable subgrain structure in this domain with the subgrain size increasing exponentially with an increase in temperature. (2) A domain exhibiting grain boundary cracking occurs at temperatures lower than 800-degrees-C and strain rates lower than 0.01 s-1. (3) A domain exhibiting intense grain boundary cavitation occurs at temperatures higher than 1075-degrees-C. The material did not exhibit a dynamic recrystallization (DRX) domain, unlike other superalloys. At strain rates higher than about 1 s-1, the material exhibits flow instabilities manifesting as kinking of the elongated grains and adiabatic shear bands. The material may be safely worked in the domain of dynamic recovery but can only be statically recrystallized.

Control de malezas en el cultivo de la soya (Glycine max L. Merril) variedad (Biloxi y hardee) 69-341

En el Centro Experimental Agropecuario La Calera, Managua, Nicaragua, se estableció en siembra de agosto a noviembre de 1976, un ensayo para determinar el tratamiento mas efectivo y rentable en el control de las malezas del cultivo de la soya (Glycine max L. Merril). Se escogió la variedad (Biloxi x Hardee) 69-341 de crecimiento determinado y ciclo vegetativo intermedio de 90-100 días. Los tratamientos que se evaluaron fueron los siguientes: Alachlor, Metribuzin, Linuron, Trifluralina, Alachlor + Metribuzin, Alachlor + Linuron, Alachlor + Trifluralina, Metribuzin + Lanuron, Metribuzin + Trifluralina, Linuron + Trifluralina en dosis de 2049,5 ml, 497,70 g, 966,00 g, 533,75 ml, 1024,75 ml + 248,85 g, 1024,75 ml + 483,00 g, 1024,75 ml + 266,87 ml, 248,85 g + 483,00 g, 248,85 g + 266,87 ml y 483,00 g, + 266,87 ml, por hectárea respectivamente, usando como comparadores un tratamiento mecánico y un testigo absoluto. Los tratamientos fueron distribuidos en un diseño de bloques completos al azar, con cuatro repeticiones. La parcela experimental consto de ocho surcos de cinco metros de largo, espaciados a cincuenta centímetros entre si y a 2,50 centímetros entre planta, correspondiendo a la parcela útil los cuatro surcos centrales a los cuales se les elimino 50,0 centímetros en cada extremo. El análisis de varianza practicado en los rendimientos de granos y en los porcentajes de control de malezas determino diferencia altamente significativa entre tratamientos al nivel de 0,01 de probabilidad de error. La mezcla de Alachlor + Metribuzin fue el tratamiento herbicida que ejerció el mayor control sobre gramíneas y hojas ancha, con 97,00 por ciento de control hasta los 60 días de emergida la soya. Los tratamientos Metribuzin, Metribuzin + Trifluralina y Alachlor fueron estadisticamente igual al nivel del 0,05 de probabilidad de error con: 74,00; 72,00 y 71;00 por ciento. Los tratamientos que menor porcentaje de control de malezas ejercieron hasta los 60 dias fueron Linuron y Linuron + Trifluralina con 34.00 por ciento. Los mayores rendimientos significativos de grano de soya, se lograron con: testigo mecanico, Alachlor + Metribuzin, Alachlor, y Alachlor + Linuron obteniendo 2,539.00, 2.294.00, 2.279.00 y 2.194.00 kilogramos por hectárea respectivamente. Los menores rendimientos correspondieron a: Trifluralina con 1,103.00 hectarea y testigo absoluto con 844.00 por hectarea. El analisis economico de los rendimientos por tratamiento, revelo que los mayores ingresos netos se obtuvieron con: testigo mecánico, Alachlor + Metribuzin, y Alachlor y Alachlor + Linuron de: 1,945.22, 1,800.12, 1,771.87 y 1,668.31 córdobas por hectárea respectivamente, pero la mayor relación beneficio-costo se logro con los tratamientos Alachlor, Alachlor + Metribuzin, testigo mecánico y Alachlor + Linuron, con 2.31, 2.30, 2.23 y 2.21 respectivamente.

Diário da Constituinte [gravação de vídeo] : [programa n. 341]

A Sessão do Plenário da Constituinte começou com os líderes de diversos partidos se revesando na tribuna a favor e contra a proposta do Centrão para a mudança do Regimento Interno. Após muita confusão e debate, é posta em votação a proposta do Centrão. O líder Mário Covas comunica que o PMDB se retira da votação. O PMDB e os Partidos Progressistas se retiram e os constituintes começam a votação. O Centrão está sozinho no Plenário. As galerias do Plenário se enchem com participantes de um evento da CUT, CGT e Contag. Vaias e chuvas de papel cobrem o Centrão a cada voto. Finda a votação, a mudança do Regimento é aprovada. Diante da impossibilidade de acordo, o presidente do PMDB, sugere que a Mesa faça um substitutivo com as alterações objeto de divergência. Ulysses Guimarães sugere a apresentação de um projeto de resolução para tentar o acordo entre os constituintes. Emendas e destaques poderão aperfeiçoar a proposta aprovada pelo Centrão.

The determination of bi- and trivalent iron in proximity, in mineral waters has gained in significance, on biological and technical grounds. This short paper describes the procedure of the determination of bivalent iron and total iron in a water sample.

PAD combination therapy (PS-341/bortezomib, doxorubicin and dexamethasone) for previously untreated patients with multiple myeloma

Summary Bortezomib (formerly PS-341) has significant activity in patients with relapsed multiple myeloma (MM), its efficacy is increased with the addition of dexamethasone and it demonstrates synergy with doxorubicin, thus providing the rationale for combination therapy with bortezomib, doxorubicin and dexamethasone (PAD). Patients with untreated MM received four 21-d cycles of PAD, comprising bortezomib 1·3 mg/m2 on days 1, 4, 8 and 11, along with dexamethasone 40 mg on days 1–4, 8–11 and 15–18 during cycle 1 and days 1–4 during cycles 2–4. During days 1–4, patients also received 0, 4·5 or 9 mg/m2 of doxorubicin at dose levels 1, 2, and 3 respectively. Following peripheral blood stem cell (PBSC) collection, patients received high-dose melphalan (MEL200) with PBSC transplantation (PBSCT). After PAD induction alone, 20 of 21 patients (95%) achieved at least a partial response (PR), including complete response (CR) in five patients (24%). Twenty of 21 had PBSC mobilized, and 18 of 20 received MEL200/PBSCT. In an intention-to-treat analysis, response rates were: CR 43%, near CR 14%, very good PR 24%, PR 14% and stable disease 5%. PAD was effective, did not prejudice subsequent PBSC collection, and should be further evaluated in prospective randomized trials.
