(379 aa), FASTA scores: opt: 163,E(): 0.00063, (32.1% identity in 112 aa overlap). Rv1413 is similar to N-terminal part of same enzyme suggesting possible frameshift. Sequence has been checked and no errors found, it is identical in Mycobacterium bovis strain AF2122/97 and in Mycobacterium tuberculosis CDC1551.

Rv2308, (MTCY339.01c), len: 238 aa. Conserved hypothetical protein, sharing similarity with O53464|Rv2018|MTV018.05 from Mycobacterium tuberculosis (239 aa), FASTA scores: opt: 142, E(): 0.034, (24.8% identity in 250 aa overlap). As contains possible helix-turn-helix motif at aa 16-37 (Sequence: YVYAEVDKLIGLPAGTAKRWIN) (Score 1169, +3.17 SD), may be a transcriptional regulator. This region is a possible MT-complex-specific genomic island (See Becq et al.,2007).

Conserved protein; Rv2216, (MTCY190.27), len: 301 aa. Conserved protein, equivalent to Mycobacterium leprae ML0860 (307 aa), Z98741|MLCB22_10 Mycobacterium leprae cosmid B22; H (307 aa).

Conserved protein; Binds to RNA polymerase (RNAP), stimulating and stabilizing the formation of stable RNAP promoter complexes up to 2-fold from principal sigma factor SigA-dependent but not alternative sigma factor SigF-dependent promoters. Increases the affinity of core RNAP for SigA, increasing the transcriptional activity of RNAP. Unlike the case in M.smegmatis or S.coelicolor, has no effect on rifampicin inhibition of transcription. Has no effect on E.coli RNAP. Belongs to the RNA polymerase-binding protein RbpA family.
