A simultaneous assay method for diacetyl and acetoin was developed to investigate the formation of diacetyl during the brewing of alcoholic beverages. A GC-MS analysis after the extraction from neutralized sample by ethyl acetate gave accurate assay results. The detection

A new method for stereospecific assignment of prochiral methyl groups in proteins is presented in which protein samples are produced using U-[(13)C]glucose and subsaturating amounts of 2-[(13)C]methyl-acetolactate. The resulting non-uniform labeling pattern allows proR and proS methyl groups to be

Acetohydroxy acid synthase (AHAS; EC 2.2.1.6) is a thiamin diphosphate (ThDP)-dependent decarboxylase-ligase that catalyzes the first common step in the biosynthesis of branched-chain amino acids. In the first stage of the reaction, pyruvate is decarboxylated and the reactive intermediate hydroxyethyl-ThDP

Diacetyl is an important food flavor compound produced by certain strains of citrate-metabolizing lactic acid bacteria. Citrate is converted to pyruvate, from which diacetyl is produced via intermediate alpha-acetolactate. This paper reports the cloning and analysis of the gene (aldB)

To demonstrate the presence of an active alpha-acetolactate decarboxylase in Streptococcus thermophilus and to investigate its physiological function. Streptococcus thermophilus CNRZ385 contains a gene encoding an alpha-acetolactate decarboxylase. Comparison of the production of alpha-acetolactate and its decarboxylation products, by the
