Rv0115, (MTV031.09), len: 386 aa. Possible hddA,D-alpha-D-heptose-7-phosphate kinase (see citation below),similar to several hypothetical proteins and sugar kinases e.g. AAK27850.1|AF324836_3 D-glycero-D-manno-heptose 7-phosphate kinase from Aneurinibacillus thermoaerophilus (341 aa); AAK80995.1|AE007802_11 Sugar kinase from Clostridium acetobutylicum (364 aa). This region is a possible MT-complex-specific genomic island (See Becq et al., 2007).

Rv0112, (MTV031.06), len: 318 aa. Possible gca,GDP-mannose 4,6-dehydratase, similar to others e g. U18320|PAU18320_1 GDP-D-mann from Pseudomonas aeruginosa (323 aa), FASTA scores: opt: 415, E(): 4.4e-21, (27.0% identity in 318 aa overlap). Similar to Rv3634c, Rv3784,etc from Mycobacterium tuberculosis. Contains PS00061 Short-chain dehydrogenases/reductases family signature. Seems to belong to the GDP-mannose 4,6-dehydratase family. Cofactor: NAD(+). This region is a possible MT-complex-specific genomic island (See Becq et al.,2007).

Conserved secreted protein; Rv0192A, len: 100 aa. Probable N-terminal part of Rv0192, which is member of family P5.17 with Rv0116c,Rv1433, Rv2518c, Rv0483. These are all predicted to be exported/membrane proteins. Rv0192A has typical N-terminal signal peptide which is functional and was identified by PhoA fusion screens: O52054 PGB14T-O1 precursor (fragment 45 AA) (see Chubb et al., 1998). Since Rv0192 misses a signal peptide this suggests that there is a frameshift in the region of the overlap with Rv0192 but none found on reinspection of sequence.

Rv2732c, (MTCY174.12c), len: 204 aa. Probable conserved transmembrane protein, similar to Q49834 hypothetical protein B2235_C1_155 from Mycobacterium leprae (209 aa), FASTA scores: opt: 932, E(): 0, (70.6% identity in 201 aa overlap). Contains PS00343 Gram-positive cocci surface proteins 'anchoring' hexapeptide. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

Multifunctional non-homologous end joining DNA repair protein LigD; With Ku forms a non-homologous end joining (NHEJ) repair enzyme which repairs DNA double-strand breaks (DSB) with reduced fidelity. Recognizes, processes and reseals DSBs, including repairs on incompatible DSB which require 3'-resection, gap filling and ligation. Anneals the 3' overhanging strands from opposing breaks to form a gapped intermediate, which then can be extended in trans by using the termini as primers for extension of the annealed break. Binds to the recessed 5'-phosphate moiety of the downstream DNA stra [...]

DNA ligase B; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair; Belongs to the ATP-dependent DNA ligase family.

DNA ligase C; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair; Belongs to the ATP-dependent DNA ligase family.

Probable histidinol dehydrogenase HisD (HDH); Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.

Probable phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase HisA; Involved in both the histidine and tryptophan biosynthetic pathways; Belongs to the HisA/HisF family.
