Glyceraldehyde-3-phosphate dehydrogenase as a moonlighting protein in bacteria

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is considered a housekeeping protein that is present in virtually all organisms, where it performs metabolic functions essential for survival. GAPDH plays an essential role in the process of energy production, and is also involved in numerous biological processes. GAPDH belongs to a subset of proteins called moonlighting proteins, in which different functions are associated with a single polypeptide chain. The multifunctionality of GAPDH has been described in pathogenic and probiotic microorganisms, in mammals and in plants. In this review, we summarize the moonlighting role of GAPDH in bacteria.

Una Nova identificació del poeta Lluís Icard, en l’entorn de Margarida de Prades i de Maria de Castella

L’obra del poeta Lluís Icard és prou coneguda. La va estudiar i editar Joaquim Molas (1962, 1984), Giuseppe Tavani (1988) n’analitzà la versificació, i la seva lírica ha tingut un cert relleu perquè fou un dels poetes que adreçaren versos a la reina viuda Margarida de Prades. En la seva producció també destaca una llarga Consolació amorosa, el primer text literari català que es fa ressò de la teoria mèdica de l’amor hereos tal com es va aplicar a la poesia cortesana (Cabré 2002). En aquest article voldríem proposar en primer lloc una nova identificació del poeta, fins ara incerta: es tractaria de Lluís Icard, donzell, documentat com a batxiller en dret des de 1423 i mort a començament de novembre de 1429. També voldríem resituar les seves cobles (i les d’altres poetes coetanis) per a la reina Margarida, i provar que la 'reina regnant' esmentada a la Consolació és Maria de Castella. Finalment, apuntem altres indicis per a la valoració històrica de la poesia d’Icard
