Webisomerase, any one of a class of enzymes that catalyze reactions involving a structural rearrangement of a molecule. Alanine racemase, for example, catalyzes the conversion of L-alanine into its isomeric (mirror-image) form, D-alanine. An isomerase called mutarotase catalyzes the conversion of α-d-glucose into β-d-glucose. cf. ligase, lyase. Xylose isomerase that can be isolated from red Chinese rice wine, which contains the bacterium Lactobacillus xylosus. This bacterium was mistakenly classified as a L. plantarum, which normally grows on the sugar L-arabinose, and rarely grown on D-xylose. L. xylosus was recognized to be distinct for its ability to grow on D-xylose. Xylose isomerase in L. xylosus has a molecular weight of about 183000 Daltons. Its optimum growth pH is about 7.5 for the L. lactis, however strains s…
