Structure-function characterization of the recombinant aspartic proteinase A1 from Arabidopsis thaliana.

Aspartic proteinases (APs) are involved in several physiological processes in plants, including protein processing, senescence, and stress response and share many structural and functional features with mammalian and microbial APs. The heterodimeric aspartic proteinase A1 from Arabidopsis thaliana (AtAP A1) was the first acid protease identified in this… CONTINUE READING
