DNA gyrase subunit A; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.

DNA gyrase inhibitor; Inhibits all the catalytic activities of DNA gyrase by preventing its interaction with DNA. Acts by binding directly to the C- terminal domain of GyrB, which probably disrupts DNA binding by the gyrase.

Uncharacterized low-complexity protein; Derived by automated computational analysis using gene prediction method: Protein Homology.

Pentapeptide repeat; Derived by automated computational analysis using gene prediction method: Protein Homology.

ATP-dependent DNA helicase RecQ; Functions in blocking illegitimate recombination, enhancing topoisomerase activity, initiating SOS signaling and clearing blocked replication forks; component of the RecF recombinational pathway; Derived by automated computational analysis using gene prediction method: Protein Homology.

Recombination protein F; 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; Belongs to the RecF family.

DNA polymerase III subunit beta; Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiation of [...]

methionine--tRNA ligase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.

Esterase; Displays esterase activity toward palmitoyl-CoA and pNP-butyrate; Derived by automated computational analysis using gene prediction method: Protein Homology.
