Probable DNA polymerase I PolA; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.

DNA polymerase III (subunit gamma/tau) DnaZ/X; DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity; Belongs to the DnaX/STICHEL family.

Probable DNA polymerase III (alpha chain) DnaE1 (DNA nucleotidyltransferase); DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity. The alpha chain is the DNA polymerase (By similarity); Belongs to the DNA polymerase type-C family. DnaE subfamily.

DNA replication and repair protein RecF (single-strand DNA binding protein); The RecF protein is involved in DNA metabolism; it is required for DNA replication and normal SOS inducibility. RecF binds preferentially to single-stranded, linear DNA. It also seems to bind ATP (By similarity).

Rv2413c, (MTCY253.07), len: 316 aa. Conserved hypothetical protein, highly similar to O33133|MLCL536.07c|ML0603|Q49756|G466975|B1937_F2_36 hypothetical 39.1 KDA protein from Mycobacterium leprae (389 aa), FASTA scores: opt: 1683, E(): 1.8e-88, (83.9% identity in 316 aa overlap). ML0603 is a putative lipoprotein with an N-terminal signal sequence and appropriately positioned prokaryotic lipoprotein lipid attachment site that is not present in Rv2413c as this seems to be 73 aa shorter. Also some similarity with various proteins from other organisms e.g. Q9RDM2|SCC123.02c putative DNA-bin [...]

Possible DNA polymerase; Rv3644c, (MTCY15C10.08), len: 401 aa. Possible DNA polymerase, equivalent to O69546|MLCB2548.29c|ML0202 hypothetical 42.7 KDA protein from Mycobacterium leprae (405 aa), FASTA scores: opt: 2180, E(): 6.1e-116, (84.4% identity in 404 aa overlap). Similar (in totality or in first 200 aa) to DNA polymerases III, delta' or gamma subunit, e.g. Q9X906|SCH5.03c putative DNA polymerase from Streptomyces coelicolor (401 aa), FASTA scores: opt: 1022,E(): 1.5e-50, (47.05% identity in 404 aa overlap); Q9RRS5|DR2410 DNA polymerase III, tau/gamma subunit from Deinococcus rad [...]

Rv3711c, (MTV025.059c), len: 329 aa. Probable dnaQ,DNA polymerase III, epsilon subunit, similar to many e.g. Q9RJ41|SCI8.12 from Streptomyces coelicolor (328 aa), FASTA scores: opt: 509, E(): 4.2e-25, (41.6% identity in 315 aa overlap); Q9JYS6|NMB1451 from Neisseria meningitidis (serogroup B) (and Q9JTR5|MA1665 from serogroup A) (470 aa), FASTA scores: opt: 247, E(): 2.6e-08, (33.15% identity in 172 aa overlap); O83649|DP3E_TREPA|DNAQ|TP0643 from Treponema pallidum (215 aa), FASTA scores: opt: 240, E(): 3.7e-08, (29.65% identity in 162 aa overlap); P03007|DP3E_ECOLI|MUTD|B0215 from Esc [...]

Rv2191, (MTCY190.02), len: 645 aa. Conserved hypothetical protein, similar to SW:DP3A_B ACSU P13267 DNA polymerase III, alpha chain (31.3% identity in 249 aa overlap) and SW:UVRC_ECOLI P07028 excinuclease ABC subunit C (25.7% identity in 230 aa overlap). Also similar to M. tuberculosis Rv3711c (dnaQ DNA polymerase III e chain) and Rv1420 (uvrC excinuclease ABC subunit C).

DNA gyrase subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to maintain chromosomes in an underwound state, while in the absence of ATP it relaxes supercoiled dsDNA. . Also catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes. Gyrase from M.tuberculosis has higher decatenation than supercoiling activity compared to E.coli; as M.tuberculosis only has 1 type II topoisomerase, gyrase has to fulfill the decatenation function of topoisomerase IV as well. At comparable c [...]
