Rv3395c, (MTCY78.33), len: 204 aa. Conserved hypothetical protein, with some similarity with RECA proteins (recombinases A) e.g. P16238|RECA_THIFE from Thiobacillus ferrooxidans (346 aa), FASTA scores: opt: 131,E(): 1.1, (31.45% identity in 140 aa overlap); Q59560|RECA_MYCSM from Mycobacterium smegmatis (349 aa),FASTA scores: opt: 121, E(): 4.4, (30.25% identity in 129 aa overlap); etc. Note that shortened since first submission to avoid overlap with Rv3395A. Equivalent to AAK47839 from Mycobacterium tuberculosis strain CDC1551 (227 aa) but shorter 23 aa.

Rv2100, (MTCY49.40), len: 550 aa. Conserved hypothetical protein. Member of Mycobacterium tuberculosis REP13E12 repeat family with Rv1148c, Rv1945, Rv3467,Rv0094c, Rv1128c, Rv1587c, Rv1702c, Rv3466, Rv1588c; To M.tuberculosis Rv3776.

Rv3074, (MTCY22D7.07c), len: 424 aa. Conserved hypothetical protein, highly similar but shorter (46 aa) to P71806|Rv1378c|MTCY02B12.12c hypothetical 51.3 KDA protein from Mycobacterium tuberculosis (475 aa), FASTA scores: opt: 2009, E(): 5.8e-113, (72.95% identity in 429 aa overlap); and also similar to other hypothetical mycobacterium proteins e.g. O33266|Rv0336|MTCY279.03 (503 aa), FASTA scores: opt: 337, E(): 7.5e-13, (28.6% identity in 381 aa overlap); O33360|Rv0515|MTCY20G10.05 (503 aa),FASTA scores: opt: 337, E(): 7.5e-13, (28.6% identity in 381 aa overlap); etc.

Conserved hypothetical protein; Catalyzes the NADPH-dependent reduction of ketopantoate into pantoic acid.

Rv1001, (MTCI237.16), len: 402 aa. Probable arcA,arginine deiminase, similar to e.g. ARCA_PSEAE|P13981 arginine deiminase (417 aa), fasta scores: opt: 581, E(): 1.4e-31, (39.4% identity in 411 aa overlap); also similar to SAGP_STRPY|P16962 streptococcal acid glycoprotein (410 aa), FASTA scores, opt: 823, E():0, (38.3% identity in 402 aa overlap). Belongs to the arginine deiminase family.

Crossover junction endodeoxyribonuclease RuvC; Nuclease that resolves Holliday junction intermediates in genetic recombination. Cleaves the cruciform structure in supercoiled DNA by nicking to strands with the same polarity at sites symmetrically opposed at the junction in the homologous arms and leaves a 5'-terminal phosphate and a 3'-terminal hydroxyl group (By similarity).

Probable bifunctional transcriptional activator/DNA repair enzyme AlkA; Is involved in the adaptive response to alkylation damage in DNA caused by alkylating agents. Repairs the Sp diastereomer of DNA methylphosphotriester lesions by a direct and irreversible transfer of the methyl group to one of its own cysteine residues. Also catalyzes the hydrolysis of the deoxyribose N-glycosidic bond to excise 3- methyladenine, 3-methylguanine, 7-methylguanine, O2-methylthymine, and O2-methylcytosine from the damaged DNA polymer formed by alkylation lesions (By similarity); In the C-terminal sect [...]

Repressor LexA; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. Has been shown to bind to the 14 bp palindromic sequence 5'-CGAACNNNNGTTCG-3'. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair.

Rv1376, (MTCY02B12.10), len: 497 aa. Conserved hypothetical protein, some similarity to hypothetical proteins from several organisms e.g. Q52872|U39409 Rhizobium leguminosarum (247 aa), FASTA scores: E(): 2.1e-12, (34.7% identity in 219 aa overlap).
