FunFam 9: Probable phosphoglucosamine mutase

There are 4 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Phosphoglucosamine mutase. [EC: 5.4.2.10]
Alpha-D-glucosamine 1-phosphate = D-glucosamine 6-phosphate.
  • The enzyme is involved in the pathway for bacterial cell-wall peptidoglycan and lipopolysaccharide biosyntheses, being an essential step in the pathway for UDP-N-acetylglucosamine biosynthesis.
  • The enzyme from Escherichia coli is activated by phosphorylation and can be autophosphorylated in vitro by alpha-D-glucosamine 1,6- bisphosphate, which is an intermediate in the reaction, alpha-D- glucose 1,6-bisphosphate or ATP.
  • It can also catalyze the interconversion of alpha-D-glucose 1-phosphate and alpha-D-glucose 6-phosphate, although at a much lower rate.

Phosphopentomutase. [EC: 5.4.2.7]
Alpha-D-ribose 1-phosphate = D-ribose 5-phosphate.
  • Also converts 2-deoxy-alpha-D-ribose 1-phosphate into 2-deoxy-D- ribose 5-phosphate.
  • Alpha-D-ribose 1,5-bisphosphate, 2-deoxy-alpha-D-ribose 1,5- bisphosphate, or alpha-D-glucose 1,6-bisphosphate can act as cofactor.
  • Formerly EC 2.7.5.6.

Phosphomannomutase. [EC: 5.4.2.8]
Alpha-D-mannose 1-phosphate = D-mannose 6-phosphate.
  • Alpha-D-mannose 1,6-bisphosphate or alpha-D-glucose 1,6-bisphosphate can act as cofactor.
  • Formerly EC 2.7.5.7.
 1 Q68BJ6
Phosphoglucomutase (alpha-D-glucose-1,6-bisphosphate-dependent). [EC: 5.4.2.2]
Alpha-D-glucose 1-phosphate = alpha-D-glucose 6-phosphate.
  • Maximum activity is only obtained in the presence of alpha-D-glucose 1,6-bisphosphate.
  • This bisphosphate is an intermediate in the reaction, being formed by transfer of a phosphate residue from the enzyme to the substrate, but the dissociation of bisphosphate from the enzyme complex is much slower than the overall isomerization.
  • Also, more slowly, catalyzes the interconversion of 1-phosphate and 6-phosphate isomers of many other alpha-D-hexoses, and the interconversion of alpha-D-ribose 1-phosphate and 5-phosphate.
  • Cf. EC 5.4.2.5.
  • Formerly EC 2.7.5.1.
