Conserved hypothetical protein; Binds to DNA and alters its conformation. May be involved in regulation of gene expression, nucleoid organization and DNA protection; Belongs to the YbaB/EbfC family.

RECF protein (recF); 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.

ATP-dependent DNA helicase (recG); Psort: bacterial inner membrane --- Certainty= 0.111(Affirmative); COG1200 RecG RecG-like helicases.

single-stranded-DNA-specific exonuclease (recJ); Psort: bacterial inner membrane --- Certainty= 0.251(Affirmative); COG0608 RecJ single-stranded DNA-specific exonuclease.

Holliday (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.

recA protein (recA); 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; Belongs to the RecA family.

Riboflavin biosynthesis protein (ribD); Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.

DNA topoisomerase I (topA); Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing D [...]

Spermidine/putrescine import ATP-binding protein (potA); Psort: bacterial cytoplasm --- Certainty= 0.231(Affirmative); COG3842 PotA ABC-type spermidine/putrescine transport systems, ATPase components; Belongs to the ABC transporter superfamily.
