GN   Name=rpoB {ECO:0000255|HAMAP-Rule:MF_01321};
OS   Enterococcus faecium (Streptococcus faecium).
OC   Bacteria; Firmicutes; Bacilli; Lactobacillales; Enterococcaceae;
OC   Enterococcus.
OX   NCBI_TaxID=1352;
RN   [1]
RP   NUCLEOTIDE SEQUENCE [GENOMIC DNA].
RC   STRAIN=38-15;
RA   Enne V.I., Bennett P.M.;
RT   "Rifampin resistance and its fitness cost in Enterococcus faecium.";
RL   Submitted (OCT-2002) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: DNA-dependent RNA polymerase catalyzes the transcription of
CC       DNA into RNA using the four ribonucleoside triphosphates as substrates.
CC       {ECO:0000255|HAMAP-Rule:MF_01321}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate +
CC         RNA(n+1); Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:14527, Rhea:RHEA-
CC         COMP:17342, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:140395;
CC         EC=2.7.7.6; Evidence={ECO:0000255|HAMAP-Rule:MF_01321};
CC   -!- SUBUNIT: The RNAP catalytic core consists of 2 alpha, 1 beta, 1 beta'
CC       and 1 omega subunit. When a sigma factor is associated with the core
CC       the holoenzyme is formed, which can initiate transcription.
CC       {ECO:0000255|HAMAP-Rule:MF_01321}.
CC   -!- SIMILARITY: Belongs to the RNA polymerase beta chain family.
CC       {ECO:0000255|HAMAP-Rule:MF_01321}.
