Abstract:Reactive intermediate deaminase A (RidA) is a highly conserved enzyme that catalyzes the hydrolysis of 2‐imino acids to the corresponding 2‐keto acids and ammonia. RidA thus prevents the accumulation of such potentially harmful compounds in the cell, as exemplified by its role in the degradation of 2‐aminoacrylate, formed during the metabolism of cysteine and serine, catalyzing the conversion of its stable 2‐iminopyruvate tautomer into pyruvate. Capra hircus (goat) RidA (ChRidA) was the first mammalian RidA to… Show more
