Names and origin
| Protein names | Recommended name: Phosphoglucosamine mutase EC=5.4.2.10 | ||||
| Gene names |
| ||||
| Organism | Methanococcus maripaludis [Complete proteome] [HAMAP] | ||||
| Taxonomic identifier | 39152 [NCBI] | ||||
| Taxonomic lineage | Archaea › Euryarchaeota › Methanococci › Methanococcales › Methanococcaceae › Methanococcus |
Protein attributes
| Sequence length | 447 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Catalyzes the conversion of glucosamine-6-phosphate to glucosamine-1-phosphate. Also catalyzes the isomerization of glucose-1-phosphate to glucose-6-phosphate, but at a 5-fold lower rate. Ref.2 |
| Catalytic activity | Alpha-D-glucosamine 1-phosphate = D-glucosamine 6-phosphate. Ref.2 |
| Cofactor | Binds 1 magnesium ion per subunit. Ref.2 |
| Subunit structure | Monomer. Also forms large aggregates. Ref.2 |
| Post-translational modification | Activated by phosphorylation. Glucose-1,6-bisphosphate or fructose-1,6-bisphosphate can activate the enzyme in vitro. However, since glucose-1,6-bisphosphate is not believed to form in methanogens, the physiologically relevant activator might be a serine kinase protein. HAMAP MF_01554 |
| Sequence similarities | Belongs to the phosphohexose mutase family. |
