2.7.7.59 |
| Accepted name: |
[protein-PII] uridylyltransferase |
| Reaction: |
UTP + [protein-PII] = diphosphate + uridylyl-[protein-PII] |
| Other name(s): |
PII uridylyl-transferase; uridyl removing enzyme |
| Systematic name: |
UTP:[protein-PII] uridylyltransferase |
| Comments: |
The enzyme uridylylates and de-uridylylates the small trimeric protein PII. The enzymes from Escherichia coli and Salmonella typhimurium have been wrongly identified, in some databases, as EC 2.7.7.12 (UDP-glucose—hexose-1-phosphate uridylyltransferase), from which it differs greatly in both reaction catalysed and sequence. |
