Identifier, protein and gene names [?]

Identifier
MODA
Protein name
RecName: Full=NAD--protein ADP-ribosyltransferase modA;
EC 2.4.2.31;
AltName: Full=RNA polymerase ADP-ribosylase modA;
Gene name
modA

Comments [?]

Function ADP-ribosyltransferase that efficiently ADP-ribosylates both alpha subunits of host RNA polymerase RPOA. The ModA-induced ADP-ribosylation of RPOA alpha subunits inhibits transcription from viral early promoters.
Catalytic activity RHEA:19149: L-arginyl-[protein] + NAD(+) = H(+) + N(omega)-(ADP-D-ribosyl)-L-arginyl-[protein] + nicotinamide
EC 2.4.2.31
Subcellular location Virion. Note=This protein is injected from the virion into the bacterial cell.
Similarity Belongs to the Tevenvirinae NAD--protein ADP-ribosyltransferase modA family.
