Isomerization of the predicted beta-D-fructose 6-phosphate
Abstract
Phosphomannose isomerase (D-mannose 6-phosphate ketol-isomerase) (EC 5.3.1.8) has been shown to use the predicted beta-D-fructose 6-phosphate as substrate. The fate of alpha-D-fructose 6-phosphate is not determined by these experiments. beta-D-Mannose 6-phosphate is not anomerized to alpha-D-mannose 6-phosphate by this enzyme.
