Summary: Phosphomannomutase catalyzes the conversion between D-mannose 6-phosphate and D-mannose 1-phosphate which is a substrate for GDP-mannose synthesis. GDP-mannose is used for synthesis of dolichol-phosphate-mannose, which is essential for N-linked glycosylation and thus the secretion of several glycoproteins as well as for the synthesis of glycosyl-phosphatidyl-inositol (GPI) anchored proteins.

What's a GeneRIF?

The 1.93 A resolution structure of PMM1 complexed with inosine monophosphate (IMP) was determined. The structure reveals IMP bound at the substrate recruitment site, thus inhibiting the mutase activity while simultaneously activating a phosphatase activity (IMP Kact = 1.5 muM) resulting from the hydrolysis of the phospho-enzyme.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
