Taxonomic identifier

78245 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rhizobiales › Xanthobacteraceae › Xanthobacter

Protein attributes

Sequence length	129 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Promotes RNA polymerase assembly. Latches the N- and C-terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits By similarity. HAMAP MF_00366
Catalytic activity	Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). HAMAP MF_00366
Subunit structure	The RNAP catalytic core consists of 2 alpha, 1 beta, 1 beta' and 1 omega subunit. When a sigma factor is associated with the core the holoenzyme is formed, which can initiate transcription By similarity.
Sequence similarities	Belongs to the RNA polymerase subunit omega family.
