α-Isopropylmalate synthase (α-IPMS) catalyzes the metal-dependent aldol reaction between α-ketoisovalerate (α-KIV) and acetyl-coenzyme A (AcCoA) to give α-isopropylmalate (α-IPM). This reaction is the first committed step in the biosynthesis of leucine in bacteria. α-IPMS is homodimeric, with monomers consisting of

Branched-chain alpha-keto acid dehydrogenase kinase (BDK) phosphorylates and inactivates the branched-chain alpha-keto acid dehydrogenase complex (BCKDC), which is the rate-limiting enzyme in the branched-chain amino acid catabolism. BDK has been believed to be bound to the BCKDC. However, recent our

The alpha-ketoisovalerate decarboxylase (Kivd) is a unique lactococcal key enzyme in the decarboxylation of branched-chain alpha-keto acids derived from branched-chain amino acids transamination into aldehydes. These products are important aroma compounds produced during cheese ripening. In this study, the Kivd
