D-tagatose 3-epimerase.
based on mapping to UniProt O50580
(1) D-tagatose = D-sorbose. (2) D-psicose = D-fructose.
-!- The enzymes isolated from the bacteria Pseudomonas cichorii, Pseudomonas sp. ST-24, Rhodobacter sphaeroides and Mesorhizobium loti catalyze 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.
