General annotation (Comments)

Function	Component of the DNA-dependent RNA polymerase that catalyzes the transcription in the cytoplasm of viral DNA into RNA using the four ribonucleoside triphosphates as substrates. Subunit 2 is the second largest component of RNA polymerase. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. DNA-dependent RNA polymerase is composed of mobile elements that move relative to each other. RPB2 is 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 By similarity.
Catalytic activity	Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).
Subunit structure	Component of the RNA polymerase that consists of at least 6 subunits Probable.
Subcellular location	Host cytoplasm Potential.
Miscellaneous	The binding of ribonucleoside triphosphate to the RNA polymerase transcribing complex probably involves a two-step mechanism. The initial binding seems to occur at the entry (E) site and involves a magnesium ion coordinated by three conserved aspartate residues of the two largest RNA Pol subunits By similarity.
Sequence similarities	Belongs to the RNA polymerase beta chain family.
