Conserved protein; Under low copper conditions, represses the expression of lpqS, Rv2963, mymT, socA, socB, mmcO and its own expression. In the presence of copper, RicR dissociates from DNA, leading to the expression of the target genes. Members of the RicR regulon are important for copper resistance during infections and full virulence in a mouse model of infection.

Rv1667c, (MTV047.03c), len: 217 aa. Probable second part of macrolide-transport ATP-binding protein ABC transporter (see citation below), with similarity to C-terminal end of putative ABC transporters/ATP binding proteins, e.g. Z99108|BSUB0005_6 ABC transporter (ATP-binding protein) homolog yfmR from Bacillus subtilis (629 aa), FASTA scores: opt: 411, E(): 6.9e-17, (37.8% identity in 217 aa overlap); etc. Similarity to other NBD components of ABC transporters suggests that Rv1667c and Rv1668c should be contiguous. However, sequence has been checked and no errors found, also same sequen [...]

Conserved hypothetical protein; Generates 3->3 cross-links in peptidoglycan, catalyzing the cleavage of the mDap(3)-D-Ala(4) bond of a tetrapeptide donor stem and the formation of a bond between the carbonyl of mDap(3) of the donor stem and the side chain of mDap(3) of the acceptor stem. Is specific for donor substrates containing a stem tetrapeptide since it cannot use pentapeptide stems.

Rv0189c, (MTCI28.28c), len: 575 aa. Probable ilvD,dihydroxy-acid dehydratase, similar to many e.g. ILVD_LACLA|Q02139 dihydroxy-acid dehydratase (dad) from Lactococcus lactis (subsp. lactis) (Streptococcus lactis) (570 aa), FASTA scores: opt: 1605, E(): 0, (46.0% identity in 561 aa overlap). Also similar to ML2608|MLCL622.06c|O06069|ILVD_MYCLE dihydroxy-acid dehydratase from Mycobacterium leprae (564 aa). Contains PS00886 Dihydroxy-acid and 6-phosphogluconate dehydratases signature 1. Belongs to the ILVD / EDD family. Cofactor: binds 1 4FE-4S cluster (potential).

Rv3756c, (MTV025.104c), len: 239 aa. Possible proZ,osmoprotectant transport integral membrane protein ABC transporter (see citation below), similar to osmoprotection proteins (proW, proZ) involved in glycine betaine/L-proline/choline transport, e.g. BAB58609|Q99RI4|OPUCB|SA2236|SAV2447 OPUCB protein (probable glycine betaine/carnitine/choline ABC transporter) from Staphylococcus aureus (211 aa) FASTA scores: opt: 434, E(): 2.5e-18, (36.6% identity in 194 aa overlap); Q45461|OPBB_BACSU|OPUBB|prow choline transport system permease protein (mediate the uptake of choline for synthesis of t [...]

Possible membrane protein; Rv3675, (MTV025.023), len: 125 aa. Possible membrane protein, with some similarity to Q9YCZ2|APE1120 hypothetical 11.7 KDA protein from Aeropyrum pernix (103 aa), FASTA scores: opt: 100, E(): 9, (40.0% identity in 55 aa overlap).

Pyridoxine 5'-phosphate oxidase; Catalyzes the oxidation of pyridoxine 5'-phosphate (PNP) into pyridoxal 5'-phosphate (PLP). Unlike many PNPOx enzymes, Rv2607 does not recognize pyridoxamine 5'-phosphate (PMP) as a substrate.

30S ribosomal protein S1 RpsA; Binds mRNA, facilitating recognition of most mRNAs by the 30S ribosomal subunit during translation initiation (By similarity). Probably plays a role in trans-translation; binds tmRNA (the product of the ssrA gene). In trans-translation Ala- aminoacylated transfer-messenger RNA (tmRNA, product of the ssrA gene; the 2 termini fold to resemble tRNA(Ala) while it encodes a short internal open reading frame (the tag peptide)) acts like a tRNA, entering the A-site of the ribosome and displacing the stalled mRNA (which is subsequently degraded). The ribosome the [...]

Probable aspartate 1-decarboxylase precursor PanD (aspartate alpha-decarboxylase); Catalyzes the pyruvoyl-dependent decarboxylation of aspartate to produce beta-alanine; Belongs to the PanD family.
