It was subsequently established that phosphomannose isomerase is a zinc-metalloenzyme containing 1 atom of zinc per enzyme molecule of 45,000 molecular weight,
Phosphoglucose isomerase (PGI) has a very similar function to PMI, (as it catalyzes the interconversion of glucose 6-phosphate and F6P) however PGI can anomerize alpha and beta G6P, and may also catalyze the conversion of alpha M6P to beta M6P, while PMI may not anomerize M6P. See more Mannose-6 phosphate isomerase (MPI), alternately phosphomannose isomerase (PMI) (EC 5.3.1.8) is an enzyme which facilitates the interconversion of fructose 6-phosphate (F6P) and mannose-6-phosphate (M6P). … See more MPI is composed of 440 amino acid residues, with one active site and one zinc ion (Zn ) ligand.
