Phosphomannose isomerase metabolic pathway
WebRibose-5-phosphate isomerase B (RpiB) was first identified in the pentose phosphate pathway responsible for the inter-conversion of ribose-5-phosphate and ribulose-5-phosphate. Though there are seldom key enzymes in central carbon metabolic system developed as useful biocatalysts, RpiB with the advantages of wide substrate scope and … 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 transport and cell membrane identification in prokaryotic and eukaryotic organisms.
