Rv0612, (MTCY19H5.09c), len: 201 aa. Conserved hypothetical protein, highly similar, but in part, to downstream ORF Rv0609A conserved hypothetical protein from Mycobacterium tuberculosis (75 aa); and showing weak similarity with other hypothetical proteins from Mycobacterium tuberculosis. Note that first start has been taken although this overlaps slightly with the upstream ORF. This region is a possible MT-complex-specific genomic island (See Becq et al., 2007).

Possible toxin VapC24. Contains PIN domain; Toxic component of a type II toxin-antitoxin (TA) system. An RNase. Its cognate antitoxin is VapB24 (By similarity). Belongs to the PINc/VapC protein family.

Possible toxin VapC20; Toxic component of a type II toxin-antitoxin (TA) system. An endoribonuclease that cleaves both E.coli and M.smegmatis 23S rRNA between G2661 and A2662 in the sarcin-ricin loop (SRL, E.coli 23S rRNA numbering). The SRL sequence is highly conserved and is implicated in GTP hydrolysis by EF-Tu and EF-G. Acts on purified ribosomes but not on isolated RNA in E.coli, nor on a shortened artificial substrate. Upon expression in E.coli inhibits cell growth, colony formation and translation. Its toxic effect is neutralized by coexpression, or subsequent expression (tested [...]

Possible toxin VapC10; Toxic component of a type II toxin-antitoxin (TA) system. An RNase. The cognate antitoxin is VapB10 (By similarity). Belongs to the PINc/VapC protein family.

PPE family protein PPE8; Rv0355c, (MTCY13E10.15c, MTCY13E10.16c,MTCY13E10.17c), len: 3300 aa.

Rv3081, (MTV013.02), len: 412 aa. Conserved hypothetical protein. Second part of the protein (approximately residues 250-412) shares weak similarity with other hypothetical proteins e.g. Q9YEU3|APE0488 from Aeropyrum pernix (188 aa), FASTA scores: opt: 149, E(): 0.019, E(): 0.019, (29.5% identity in 173 aa overlap); and first part shares weak similarity with C-terminal part of Q9RVT9|DR0933 alpha-amlyase from Deinococcus radiodurans (644 aa), FASTA scores: opt: 127, E(): 1.4, (27.25% identity in 198 aa overlap). Equivalent to AAK47502|MT3166 hypothetical 48.3 KDA protein from Mycobacte [...]

Rv3350c, (MTV004.07c), len: 3716 aa. PPE56, Member of the Mycobacterium tuberculosis PPE family of Gly-, Ala-,Asn-rich proteins, similar to many Mycobacterium tuberculosis proteins from strains H37Rv and CDC1551, e.g. O50378|Rv3347c|MTV004.03c (3157 aa), FASTA scores: opt: 6497, E(): 0, (61.65% identity in 3756 aa overlap); MTCY28_16, MTV050_2, MTY13E10_17, MTCY63_10, MTCY180_1,MTCY63_9, MTV050_1, MTV014_3, MTY13E10_15; etc.

Rv3347c, (MTV004.03c), len: 3157 aa. PPE55, Member of the Mycobacterium tuberculosis PPE family, Gly-, Ala-,Asn-rich protein. Similar to many from Mycobacterium tuberculosis strains H37Rv and CDC1551, e.g. O50379|Rv3350c|MTV004.07c (3716 aa), FASTA scores: opt: 6497, E(): 0, (61.65% identity in 3756 aa overlap); and other upstream ORFs MTV004_5, MTY13E10_15, MTCY28_16,MTCY63_9, MTY13E10_17, MTCY180_1; etc. Predicted possible vaccine candidate (See Zvi et al., 2008).
