CLASS: IC: C12N009-02; C12P007-42; C12P007-40; C12N001-20. APPLICATION: DE 83-3320495 7 Jun 1983. DOCUMENT TYPE: Patent CA Section: 7 (Enzymes) Section cross-reference(s): 9 D-2-Hydroxy-4-methylpentanoate dehydrogenase (I) is isolated by std. methods from various species of Lactobacillus and Leuconostoc and is used for the stereospecific dehydrogenation of D-2-hydroxy-4-methylpentanoate and other D-2-hydroxy acids to the corresponding 2-oxo acids, as well as for the stereospecific redn. of 2-oxo-4-methylpentanoate and other 2-oxo acids to the corresponding D-2-hydroxy acids. Thus, crude exts. from 45 different strains of Lactobacillus and Leuconostoc were tested for the presence of I by incubating the exts. with 2-oxo-4-methylpentanoate and NADH at pH 7.0 and measuring the decrease in absorbance at 340 nm. The stereospecificity of the reaction was tested was tested by using D- and L-2-hydroxy-4-methylpentanoate and NAD as substrates, and showing that the L-hydroxy compd. was not converted to product. The activity with other 2-oxo acids was also tested. Of the organisms studied, Lactobacillus casei pseudoplantarum had the broadest substrate spectrum, whereas Leuconostoc oenos had the highest specific activity with 2-oxo-4-methylpentanoate as substrate. Km Values were detd. for all substrates, and pH optima and storage stability were also detd. .
