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

2-Ketoisovalerate is used as a therapeutic agent, and a 2-ketoisovalerate-producing organism may serve as a platform for products deriving from this 2-keto acid. We engineered the wild type of Corynebacterium glutamicum for the growth-decoupled production of 2-ketoisovalerate from glucose by

A strategy for the introduction of ((1)H,(13)C-methyl)-alanine into perdeuterated proteins is described. Specific protonation of alanine methyl groups to a level of 95% can be achieved by overexpressing proteins in M9/D(2)O based bacterial growth medium supplemented with 800 mg/l of

Chain elongated, methionine (Met)-derived glucosinolates are a major class of secondary metabolites in Arabidopsis (Arabidopsis thaliana). The key enzymatic step in determining the length of the chain is the condensation of acetyl-coenzyme A with a series of omega-methylthio-2-oxoalkanoic acids, catalyzed
