Description
Dihydrodipicolinate synthase is the first enzyme unique to lysine biosynthesis, catalyzing the condensation of pyruvate and aspartate β-semialdehyde by a ping-pong mechanism. It also catalyzes the rate-limiting step in E.coli lysine biosynthesis after aspartate kinase III. The condensing enzyme-pyruvate complex, prior to reduction and hydrolysis, exists as the Schiff base formed between the carbonyl of pyruvate and an ε-amino group of a lysine residue on the enzyme. This property classifies the enzyme as a Class I aldolase with respect to carbon-carbon bond formation. The enzyme is inhibited by lysine, a feedback inhibitor. (source: Ecocyc)
