Towards the biotechnological isomerization of branched sugars: d-tagatose-3-epimerase equilibrates both enantiomers of 4-C-methyl-ribulose with both enantiomers of 4-C-methyl-xylulose
摘要:
Microbial oxidation of 2-C-methyl-D-ribitol and 2-C-methyl-D-arabinitol by Gluconobacter thailandicus NBRC 3254 produces 4-C-methyl-L-ribulose and 4-C-methyl-D-ribulose, respectively. Further, 4-C-methyl-L-ribulose and 4-C-methyl-D-ribulose were equilibrated by D-tagatose-3-epimerase (DTE) with 4-C-methyl-L-Xylulose and 4-C-methyl-D-XY11110se, respectively. These transformations demonstrate that polyol dehydrogenase and DTE act on branched synthetic sugars. The green preparation of all of the stereoisomers of 4-C-methyl pentuloses illustrates the ability of biotechnology to generate novel branched mono saccharides. (c) 2008 Elsevier Ltd.
