Function
function
ADP-ribosyltransferase that efficiently ADP-ribosylates one of the two alpha subunits of host RNA polymerase RPOA on an arginine located in the C-terminal region. ADP-ribosylation of RPOA alpha subunit enhances the transcription of viral early genes. Also ribosylates RPOA subunits beta, beta' and sigma 70 and performs an autoribosylation reaction.
Catalytic activity
- L-arginyl-[protein] + NAD+ = N(omega)-(ADP-D-ribosyl)-L-arginyl-[protein] + nicotinamide + H+
