Hypothetical protein; MPN336(new), 501(Himmelreich et al., 1996); bidomain: nucleotidyl transferase and conserved hypothetical second domain, probably phosphopantetheine adenylyltransferase activity.

phenylalanyl-tRNA synthetase beta chain; MPN106(new), 049(Himmelreich et al., 1996); Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.

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 [...]

Fructose-permease IIBC component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in fructose transport.

Hemk family protein; MPN362(new), 475(Himmelreich et al., 1996); similar to methyltransferase (S-adenosyl-methionine dependent).

ATP synthase gamma chain; Produces ATP from ADP in the presence of a proton gradient across the membrane. The gamma chain is believed to be important in regulating ATPase activity and the flow of protons through the CF(0) complex.
