A partially purified yeast enzyme is described which catalyzes specifically the conversion of α-mannose-1-phosphate to mannos-6-phosphate. This enzyme has been named phosphomannomutase. The enzyme is inactive in the absence of α-glucose-1,6-diphosphate or α-mannose-1,6-diphosphate. The apparent Michaelis constant of either coenzyme is approximately 1.5·10-4 M. Evidence is presented that phosphomannomutase is distinct from phosphoglucomutase.
