Protein

Phosphoacetylglucosamine mutase 2

Gene

SPAC1296.01c

Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the conversion of GlcNAc-6-P into GlcNAc-1-P during the synthesis of uridine diphosphate/UDP-GlcNAc, which is a biosynthetic precursor of chitin and also supplies the amino sugars for N-linked oligosaccharides of glycoproteins.By similarity

Catalytic activityi

N-acetyl-alpha-D-glucosamine 1-phosphate = N-acetyl-D-glucosamine 6-phosphate.By similarity

Cofactori

Mg2+By similarityNote: Binds 1 Mg2+ ion per subunit.By similarity

Pathwayi: UDP-N-acetyl-alpha-D-glucosamine biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes N-acetyl-alpha-D-glucosamine 1-phosphate from alpha-D-glucosamine 6-phosphate (route I).By similarity
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Glucosamine 6-phosphate N-acetyltransferase (gna1)
  2. Phosphoacetylglucosamine mutase 2 (SPAC1296.01c), Phosphoacetylglucosamine mutase 1 (SPAC13C5.05c)
This subpathway is part of the pathway UDP-N-acetyl-alpha-D-glucosamine biosynthesis, which is itself part of Nucleotide-sugar biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes N-acetyl-alpha-D-glucosamine 1-phosphate from alpha-D-glucosamine 6-phosphate (route I), the pathway UDP-N-acetyl-alpha-D-glucosamine biosynthesis and in Nucleotide-sugar biosynthesis.
