• DBTBS entry: no entry

• SubtiList entry: [1]

Additional information

The protein is sometimes annotated as omega1 subunit of RNA polymerase, however, there is no experimental evidence in support of this ("it is unrelated in sequence to ω/Rpb6 from the eubacteria, archaea and eukaryotes, unpublished data suggests it does not bind at the same site as ω/Rpb6 subunits bind their cognate RNAPs, and therefore it is unlikely to function as a true ω subunit") PubMed
