Rv2344c, (MT2409, MTCY98.13c), len: 431 aa. Probable dgt, deoxyguanosine triphosphate triphosphohydrolase,equivalent to Q9CCG3|DGT|ML0831 putative deoxyguanosine triphosphate triphosphohydrolase from Mycobacterium leprae (429 aa), FASTA scores: opt: 2316, E(): 1.6e-137, (83.85% identity in 421 aa overlap); and O52199|DGTP_MYCSM|AF027507_2 deoxyguanosinetriphosphate triphosphohydrolase from Mycobacterium smegmatis (428 aa),FASTA scores: opt: 1991, E(): 3.4e-117, (73.5% identity in 422 aa overlap). Also highly similar or similar to several deoxyguanosine triphosphate hydrolases e.g. Q9L2 [...]

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.

Probable GTP-binding protein EngA; GTPase that plays an essential role in the late steps of ribosome biogenesis; Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. EngA (Der) GTPase 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.

Probable ribonuclease RphA (RNase PH) (tRNA nucleotidyltransferase); Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation.

RNA polymerase sigma factor SigA (sigma-A); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth (Probable); Belongs to the sigma-70 factor family. RpoD/SigA subfamily.

RNA polymerase sigma factor SigB; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. A non-essential principal sigma factor that responds to cell envelope stress and hypoxia. Controls a regulon of about 40 genes, with another 100 genes expression being altered during SDS stress and about 50 gene being altered during diamide (oxidative) stress.

RecA protein (recombinase A) [contains: endonuclease PI-MTUI (MTU RecA intein)]; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage.

DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
