Transcription antitermination factor; Participates in transcription elongation, termination and antitermination. Stimulates RNA polymerase pausing at U107 and U144 in the trp leader. NusG-stimulated pausing is sequence specific. Does not affect trp leader termination.

Transcriptional terminator Rho; Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA- dependent ATPase activity, and release of the mRNA from the DNA template.

Transcription translation coupling factor involved in Rho-dependent transcription termination; Participates in both transcription termination and antitermination.

6,7-dimethyl-8-ribityllumazine synthase, beta subunit; Catalyzes the formation of 6,7-dimethyl-8-ribityllumazine by condensation of 5-amino-6-(D-ribitylamino)uracil with 3,4-dihydroxy-2- butanone 4-phosphate. This is the penultimate step in the biosynthesis of riboflavin. Is able to use the non-natural R enantiomer of 3,4- dihydroxy-2-butanone 4-phosphate as a substrate, but with less efficiency than the natural S enantiomer. Cannot use unphosphorylated 3,4-dihydroxy-2-butanone, 3,4-dihydroxy-2-butanone 3-phosphate or diacetyl as substrates.

RNA polymerase (alpha subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

Omega subunit of RNA polymerase; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits (By similarity).

Inositol monophosphatase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the inositol monophosphatase superfamily.

methionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.

Transcription elongation factor; Necessary for efficient RNA polymerase transcription elongation past template-encoded arresting sites. The arresting sites in DNA have the property of trapping a certain fraction of elongating RNA polymerases that pass through, resulting in locked ternary complexes. Cleavage of the nascent transcript by cleavage factors such as GreA or GreB allows the resumption of elongation from the new 3'terminus. GreA releases sequences of 2 to 3 nucleotides (By similarity); Belongs to the GreA/GreB family.
