ATP-dependent protease HslVU (ClpYQ), ATPase subunit; ATPase subunit of a proteasome-like degradation complex; this subunit has chaperone activity. The binding of ATP and its subsequent hydrolysis by HslU are essential for unfolding of protein substrates subsequently hydrolyzed by HslV. HslU recognizes the N-terminal part of its protein substrates and unfolds these before they are guided to HslV for hydrolysis.

ATP-dependent protease HslVU (ClpYQ), peptidasesubunit; Protease subunit of a proteasome-like degradation complex believed to be a general protein degrading machinery.

DNA topoisomerase I; 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 DNA supe [...]

Site-specific recombinase; Site-specific tyrosine recombinase, which acts by catalyzing the cutting and rejoining of the recombining DNA molecules. The XerC- XerD complex is essential to convert dimers of the bacterial chromosome into monomers to permit their segregation at cell division. It also contributes to the segregational stability of plasmids.

Lactose permease; Responsible for transport of beta-galactosides into the cell, with the concomitant uptake of protons (symport system), and also for transport of homologous and heterologous exchange of beta-galactosides.

Glucose inhibited division protein; Catalyzes the folate-dependent formation of 5-methyl-uridine at position 54 (M-5-U54) in all tRNAs; Belongs to the MnmG family. TrmFO subfamily.

PTS system, fructose-specific enzyme IIABC component.

Putative 3-carboxymuconate cyclase.
