GCW_03530

Uniprot: A0A0F6CLB1
Description: DNA-directed RNA polymerase subunit alpha
EC number: 2.7.7.6
Annotation score: 2 out of 5
Miscellaneous [CC]:
Protein existence: Inferred from homology
Catalytic activity: CATALYTIC ACTIVITY: Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). {ECO:0000256|HAMAP-Rule:MF_00059}.
Cofactor:
Enzyme regulation:
Function [CC]: FUNCTION: DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. {ECO:0000256|HAMAP-Rule:MF_00059}.
