Rv1682, (MTCI125.04), len: 305 aa. Probable coiled-coil structural protein, weakly similar to many paramyosins, kinesins and plectins e.g. MYSP_ONCVO|Q02171 paramyosin from onchocerca volvulus (879 aa), fasta scores: opt: 180, E():2.6e-08, (24.4% identity in 234 aa overlap). Also similar to Mycobacterium tuberculosis hypothetical coiled-coil proteins (wag31 antigen 84) Rv2145c and Rv2927c.

Conserved protein; Rv3732, (MTV025.080), len: 352 aa. Conserved protein. The region between aa 175-352 is highly similar to the region between aa 72-257 of Q9KH39 hypothetical 55.5 KDA protein from Mycobacterium smegmatis (511 aa), FASTA scores: opt: 1122, E(): 7.3e-63, (98.85% identity in 176 aa overlap). Also shows some similarity with Q55304 hypotheticalk protein from Synechocystis sp. strain PCC 6803 (387 aa), FASTA scores: opt: 201, E(): 2.7e-05, (27.1% identity in 251 aa overlap); and P74254|SLR1173 hypothetical 52.5 KDA protein from Synechocystis sp. strain PCC 6803 (463 aa), FA [...]

Conserved protein; Oxidase that catalyzes the conversion of cysteine to 3- oxoalanine on target proteins. 3-oxoalanine modification, which is also named formylglycine (fGly), occurs in the maturation of arylsulfatases and some alkaline phosphatases that use the hydrated form of 3- oxoalanine as a catalytic nucleophile.

Conserved hypothetical protein; Cell-wall hydrolase that hydrolyzes the amide bond between N- acetylmuramic acid and L-alanine in cell-wall glycopeptides. Is able to hydrolyze the cell walls of several bacterial species (i.e. Paenibacillus sp., B.avium, E.coli DH5alpha, E.aerogenes, L.acidophilus, B.thuringiensis, B.pumilus, B.subtilis and E.coli W3110), thereby showing that it is a cell-wall hydrolase with broad-spectrum activity. May have a role in peptidoglycan fragment recycling. Belongs to the N-acetylmuramoyl-L-alanine amidase 3 family.

Probable LYTB-related protein LytB2; Catalyzes the conversion of 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate (HMBPP) into a mixture of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Acts in the terminal step of the DOXP/MEP pathway for isoprenoid precursor biosynthesis. Has a higher activity compared with LytB2. Is essential for M.tuberculosis growth in vitro.

Rv0063, (MTV030.06), len: 479 aa. Possible oxidoreductase, similar to many. Similar to Mycobacterium tuberculosis proteins e.g. Rv3107c, Rv1257c, etc. Contains PS00862 Oxygen oxidoreductases covalent FAD-binding site.

Rv3209, (MTCY07D11.17c), len: 186 aa. Conserved hypothetical thr-, pro-rich protein, equivalent (but shorter 36 aa in N-terminus) to Q9CCH2|ML0813 putative membrane protein from Mycobacterium leprae (195 aa), FASTA scores: opt: 508, E(): 1.4e-15, (58.4% identity in 185 aa overlap). Also some similarity with Q10390|MMS3_MYCTU|MMPS3|Rv2198c|MT2254|MTCY190.09c probable conserved transmembrane transport protein from M. tuberculosis (299 aa), FASTA scores: opt: 339, E(): 3.7e-08, (35.0% identity in 180 aa overlap); and Q9CCE9|MMPS3|ML0877 putative membrane protein from Mycobacterium leprae [...]

Rv0315, (MTCY63.20), len: 294 aa. Possible beta-1,3-glucanase precursor (has hydrophobic stretch in its N-terminal part), similar to others e.g. Q51333|AAC44371.1 beta-1,3-glucanase II a from Oerskovia xanthineolytica (306 aa), FASTA scores: opt: 76, E(): 3e-14, (34.1% identity in 302 aa overlap); and AAC38290.1|AF052745 beta-1,3-glucanase II from Oerskovia xanthineolytica (435 aa). Contains glycosyl hydrolases family 16 active site signature (PS01034).

Rv1090, (MTV017.43), len: 151 aa. Probable celA2b,second part of cellulase (endoglucanase), similar to C-terminus of others e.g. O08468 cellulase CEL2 from Streptomyces halstedi (377 aa), FASTA scores: opt: 554,E(): 1.2e-30, (52.0% identity in 152 aa overlap); etc. Gene appears to have been inactivated by frameshift mutations but no errors could be found that would account for this. This region is a possible MT-complex-specific genomic island (See Becq et al., 2007); Belongs to the glycosyl hydrolase 12 (cellulase H) family.
