Glossary: | D-psicose = D-ribo-hex-2-ulose | ||||||||
Other name(s): | L-ribulose 3-epimerase; ketose 3-epimerase | ||||||||
Systematic name: | D-tagatose 3-epimerase | ||||||||
Comments: | The enzymes isolated from the bacteria Pseudomonas cichorii [2], Pseudomonas sp. ST-24 [1], Rhodobacter sphaeroides [3] and Mesorhizobium loti [4] catalyse the epimerization of various ketoses at the C-3 position, interconverting D-fructose and D-psicose, D-tagatose and D-sorbose, D-ribulose and D-xylulose, and L-ribulose and L-xylulose. The specificity depends on the species. The enzymes from Pseudomonas cichorii and Rhodobacter sphaeroides require Mn2+ [2,3]. | ||||||||
