Possible exported protein; Rv0633c, (MTCY20H11.14c), len: 279 aa. Possible exported protein; has hydrophobic stretch at aa 23-41.

Rv2168c, (MTV021.01c), len: 108 aa. Putative transposase for IS6110 (fragment), identical to many other Mycobacterium tuberculosis IS6110 transposase subunits e.g. Q50686|YIA4_MYCTU Insertion element IS6110 hypothetical 12.0 kDa protein (108 aa), fasta scores: E(): 1.4e-43,(100.00% identity in 108 aa overlap). The transposase described here may be made by a frame shifting mechanism during translation that fuses Rv2167c and Rv2168c, the sequence UUUUAAAG (directly upstream of Rv2167c) maybe responsible for such a frameshifting event (see McAdam et al., 1990).

Rv0759c, (MTCY369.04c), len: 110 aa. Conserved hypothetical protein, highly similar (but shorter 45 aa in N-terminus) to P49774|YHIT_MYCLE|ML2237|MLCB5.04c|U296A hypothetical hit-like protein from Mycobacterium leprae (155 aa), FASTA scores: opt: 766, E(): 0, (78.7% identity in 150 aa overlap). Also highly similar (but N-terminus always shorter) to hit-like proteins and protein kinase inhibitors e.g. AAF72728.1|AF265258_1|AF265258 hit-like protein from Rhodococcus sp. (141 aa); NP_212513.1|NC_001318 protein kinase C1 inhibitor (pkcI) from Borrelia burgdorferi (149 aa); P94252|YHIT_BORB [...]

Rv2169c, (MTV021.02c), len: 134 aa. Probable conserved transmembrane protein, with orthologs in M. leprae, ML0904 probable membrane protein (134 aa), and Streptomyces coelicolor. FASTA scores with ML0904, opt: 767, E(): 5.1e-43; 86.567% identity in 134 aa overlap. emb|CAA18678.1| (AL022602) >gi|13092974|emb|CAC31285.1| (AL583920). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

Mycothiol conjugate amidase Mca (mycothiol S-conjugate amidase); A mycothiol (MSH, N-acetyl-cysteinyl-glucosaminyl-inositol) S-conjugate amidase, it recycles conjugated MSH to the N-acetyl cysteine conjugate and the MSH precursor. Involved in MSH-dependent detoxification of a number of alkylating agents and antibiotics. Activity is specific for the mycothiol moiety. Has a low but measurable deacetylation activity on GlcNAc-Ins (N-acetyl-glucosaminyl-inositol), and thus can also directly contribute to the production of MSH.

Methylated-DNA--protein-cysteine methyltransferase; Involved in the cellular defense against the biological effects of O6-methylguanine (O6-MeG) and O4-methylthymine (O4-MeT) in DNA. Repairs the methylated nucleobase in DNA by stoichiometrically transferring the methyl group to a cysteine residue in the enzyme. This is a suicide reaction: the enzyme is irreversibly inactivated.

Probable proline iminopeptidase Pip (prolyl aminopeptidase) (pap); Rv0840c, (MTV043.33c), len: 286 aa. Possible pip,proline iminopeptidase, similar to many e.g. P46541|PIP_BACCO proline iminopeptidase from bacillus coagulans (288 aa), FASTA scores: opt: 657, E(): 0, (37.6% identity in 282 aa overlap); NP_386922.1|NC_003047 putative proline iminopeptidase protein from Sinorhizobium meliloti (296 aa); etc. Belongs to peptidase family S33.

GCN5-related N-acetyltransferase, MshD; Catalyzes the transfer of acetyl from acetyl-CoA to desacetylmycothiol (Cys-GlcN-Ins) to form mycothiol. Belongs to the acetyltransferase family. MshD subfamily.

Rv0795, (MTV042.05), len: 108 aa. Putative transposase for IS6110 (fragment), identical to Q50686 insertion element IS6110 (108 aa), FASTA score: (100.0 % identity in 108 aa overlap). The transposase described here may be made by a frame shifting mechanism during translation that fuses Rv0795 and Rv0796, the sequence UUUUAAAG (directly upstream of Rv0796) maybe responsible for such a frameshifting event (see McAdam et al., 1990).
