Function
KET3E_ARTGO Catalyzes the reversible C-3 epimerization of several ketoses. Shows the highest enzymatic activity for the epimerization of L-ribulose to L-xylulose. Is also able to convert D-allulose (also known as D-psicose) to D-fructose and, to a lesser extent, L-tagatose to L-sorbose, D-ribulose to D-xylulose, L-allulose to L-fructose and D-tagatose to D-sorbose.[1] [2]
