DNA gyrase subunit B; 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.

Conserved hypothetical protein; Product name confidence: Class 4 (Homologs of previously reported genes of unknown function, or no similarity to any previously reported sequences).

Major intrinsic multiple antibiotic resistance efflux outer membrane protein OprM precursor; The outer membrane component of the MexAB-OprM efflux system that confers multidrug resistance. Also functions as the major efflux pump for n-hexane and p-xylene efflux. Over-expression of the pump increases antibiotic and solvent efflux capacities. Can replace the OprJ outer membrane component of the MexCD-OprJ pump; the antibiotics exported are those exported by the intact MexCD pump, showing that efflux substrate specificity is not conferred by this component. Serves as the outer membrane co [...]

Multidrug resistance operon repressor MexR; Repressor of the mexAB-oprM multidrug resistance operon. Also represses its own expression. Many variants lead to increased expression of the mexAB-oprM operon.

Cell division topological specificity factor MinE; Prevents the cell division inhibition by proteins MinC and MinD at internal division sites while permitting inhibition at polar sites. This ensures cell division at the proper site by restricting the formation of a division septum at the midpoint of the long axis of the cell.

Transcriptional regulator NfxB; Confers resistance to guinolones. May negatively regulate the expression of genes that are associated with cell permeability to drugs.

Hypothetical protein; Product name confidence: Class 4 (Homologs of previously reported genes of unknown function, or no similarity to any previously reported sequences).

Basic amino acid, basic peptide and imipenem outer membrane porin OprD precursor; Porin with a specificity for basic amino acids. Also possesses serine protease activity; Belongs to the outer membrane porin (Opr) (TC 1.B.25) family.

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