Comments
Comments	transcription antitermination has not been reported in any mycoplasma [PUB_0182]; rho not essential in B. subtilis [PUB_0234]; the five sequenced members of the pneumoniae clade all contain most of the necessary machinery for forming an [PUB_0182]; binds RNA polymerase and promotes termination at certain RNA hairpin structures [PUB_0110]; binds Rho and RNA polymerase [PUB_0233]; helps bind Rho to elongation complex [PUB_0233]; slows RNA polymerase by enhancing pausing [PUB_0233];
