Phosphomannose isomerase function
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. Amino acids GLN 111A, HIS 113A, GLU 138A, HIS 285A, and HOH 798A are involved with the zinc ligand bonding. Structure differs from phosphoglucose … See more PMI may be helpful in the development of new antifungal treatments, as lack of PMI activity in yeast cells can lead to cell lysis and the enzyme may … See more 1. ^ EBI Database, IPRO16305 Mannose-6-phosphate Isomerase. 2. ^ "1pmi".

In humans a mechanism has been suggested which … See more PMI has several contributions to necessary metabolic pathways. It enables cells to transform M6P into F6P, which can then be entered into Glycolysis. PMI also allows cells to convert F6P into M6P, which is a common glycolytic cellular identifier for cellular … See more • Congenital disorder of glycosylation • MPI-CDG See more Webjournals.asm.org
