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.

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

DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.

Methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation; Belongs to the class-I aminoacyl-tRNA synthetase family. MetG type 2B subfamily.

ABC transporter, ATP-binding/permease protein (fragment); Catalyzes the transfer of an acyl group from acyl-phosphate (acyl-PO(4)) to glycerol-3-phosphate (G3P) to form lysophosphatidic acid (LPA). This enzyme utilizes acyl-phosphate as fatty acyl donor, but not acyl-CoA or acyl-ACP.

Manganese-dependent inorganic pyrophosphatase.

Cell division protein FtsA; Cell division protein that is involved in the assembly of the Z ring. May serve as a membrane anchor for the Z ring. Belongs to the FtsA/MreB family.

6 Protein of unknown function, without similarity to other proteins.
