|
|
|
|
|
|
||
| UniProt code: Q859P9. |
|
||
| Organism: | |
Enterobacteria phage N4 (Bacteriophage N4). |
| Taxonomy: | |
Viruses; Duplodnaviria; Heunggongvirae; Uroviricota; Caudoviricetes; Caudovirales; Podoviridae; Enquatrovirus. |
|
||
|
||
| Function: | |
DNA-dependent RNA polymerase, which is injected into the host upon infection and transcribes the phage early genes from promoters that have a 5-bp stem-3 nt loop hairpin structure. {ECO:0000269|PubMed:18362338, ECO:0000269|PubMed:19061645}. |
|
||
| Catalytic activity: | |
Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate + RNA(n+1); Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:11128, Rhea:RHEA- COMP:11129, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:83400; EC=2.7.7.6; Evidence={ECO:0000269|PubMed:21321236}; |
| Cofactor: | |
