DNA-directed RNA polymerase subunit beta

UniProtKB accession:  A0A2X0RU95

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalytic component of the DNA-directed RNA polymerase (RNAP) that catalyzes the transcription in the cytoplasm of viral DNA into RNA using the four ribonucleoside triphosphates as substrates (By similarity). Forms the polymerase active center together with RPB1 (By similarity). Part of the core element with the central large cleft, the clamp element that moves to open and close the cleft and the jaws that are thought to grab the incoming DNA template.
