Chains	Enzyme Name	Description	Catalytic Residues
A	mannose-6-phosphate isomerase (type I) M-CSA #880	Mannose-6-phosphate isomerase or phosphomannose isomerase (EC:5.3.1.8) (PMI) is the enzyme that catalyses the interconversion of mannose-6-phosphate and fructose-6-phosphate. In eukaryotes PMI is involved in the synthesis of GDP-mannose, a constituent of N- and O-linked glycans and GPI anchors and in prokaryotes it participates in a variety of pathways, including capsular polysaccharide biosynthesis and D-mannose metabolism. PMIs in this entry belong to the cupin superfamily whose functions range from isomerase and epimerase activities involved in the modification of cell wall carbohydrates in bacteria and plants, to non-enzymatic storage proteins in plant seeds, and transcription factors linked to congenital baldness in mammals [PMID: 11165500].
