Rv0912, (MTCY21C12.06), len: 149 aa. Probable conserved transmembrane protein, equivalent to Q50121|NP_302397.1|NC_002677 conserved hypothetical protein from Mycobacterium leprae (144 aa), FASTA scores: opt: 677,E(): 6.9e-38, (69.5% identity in 141 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

Rv0887c, (MTCY31.15c), len: 152 aa. Conserved hypothetical protein, highly similar to others e.g. NP_436346.1|NC_003037 Hypothetical protein from Sinorhizobium meliloti (149 aa); AL132644|SCI8_26 hypothetical protein from Streptomyces coelicolor (194 aa),FASTA scores: opt: 220, E(): 1.5e-07, (33.6% identity in 131 aa overlap); etc. Also shows weak similarity with transposases and related proteins.

Conserved protein; Rv0911, (MTCY21C12.05), len: 257 aa. Conserved protein, showing similarity with hydroxylases and hypothetical proteins e.g. T35325 probable hydroxylase from Streptomyces coelicolor (265 aa); Q54242 hypothetical protein from Streptomyces, FASTA scores: opt: 372, E(): 8.8e-18, (32.0% identity in 256 aa overlap); AAD04716.1|U77891 doxorubicin biosynthesis enzyme DnrV from Streptomyces peucetius (275 aa); AAA63051.1|U15184 hypothetical protein from Mycobacterium leprae (94 aa); etc. Also similar to Rv0577 hypothetical protein from Mycobacterium tuberculosis (261 aa).

Succinate-semialdehyde dehydrogenase [NADP+] dependent (SSDH) GabD1; Catalyzes the NADP(+)-dependent oxidation of succinate semialdehyde to succinate. It is believed to be the main source of succinate semialdehyde dehydrogenase activity in Mycobacterium. NAD(+) can substitute for NADP(+), but enzymatic activity is three times reduced.

Rv0180c, (MTCI28.20c), len: 452 aa. Probable conserved transmembrane protein, equivalent to CAC32132.1|AL583926 probable conserved membrane protein from Mycobacterium leprae (465 aa). Shows some similarity with others membrane proteins e.g. AL096849|SCI11_29 from Streptomyces coelicolor (354 aa), FASTA scores: opt: 190,E(): 0.00067, (25.9% identity in 409 aa overlap).

Possible succinate-semialdehyde dehydrogenase [NADP+] dependent (SSDH) GabD2; Catalyzes the NADP(+)-dependent oxidation of succinate semialdehyde to succinate. Although it has succinate semialdehyde dehydrogenase activity, is likely to act physiologically on a different aldehyde(s). NAD(+) can substitute for NADP(+), but enzymatic activity is three times reduced.

Antitoxin VapB15; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of cognate toxin VapC15. Partially inhibits the RNase activity of VapC15.

Possible lysophospholipase; Involved in the hydrolysis of exogenous host lipids during chronic infection. Catalyzes the hydrolysis of both monoacylglycerols (MAG) and diacylglycerols (DAG). It hydrolyzes 2-MAG, 1-3-MAG and MAG with short, medium and long chain fatty acids such as 1-monobutyroyl- rac-glycerol (MC4), 1-mono-octanoyl-rac-glycerol (MC8), 1-monodecanoyl- rac-glycerol (MC10), 1-monolauroyl-rac-glycerol (MC12), 1- monomyristoyl-rac-glycerol (MC14) and 1-mono-oleyl-rac-glycerol (MC18:1). Also able to hydrolyze DAG with short (DiC6) and medium (DiC10) fatty acid chains, but not [...]

Toxin VapC15; Toxic component of a type II toxin-antitoxin (TA) system. Degrades total E.coli RNA, which is partially inhibited by cognate antitoxin VapB15. Upon expression in M.smegmatis inhibits colony formation, which is neutralized by coexpression with VapB15.
