RNA polymerase, omega subunit; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.

Glutamate synthase, large subunit; Catalyzes the conversion of L-glutamine and 2-oxoglutarate into two molecules of L-glutamate.

Nitrate reductase 1, alpha subunit; The nitrate reductase enzyme complex allows E.coli to use nitrate as an electron acceptor during anaerobic growth. The alpha chain is the actual site of nitrate reduction.

GNAT family putative N-acetyltransferase; Belongs to the acetyltransferase family.

Polynucleotide phosphorylase/polyadenylase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. Also involved, along with RNase II, in tRNA processing. RNases II and R contribute to rRNA degradation during starvation, while RNase R and PNPase are the major contributors to quality control of rRNA during steady state growth.

Endoribonuclease; Endoribonuclease that plays a central role in RNA processing and decay. Required for the maturation of 5S and 16S rRNAs and the majority of tRNAs. Also involved in the degradation of most mRNAs. Can also process other RNA species, such as RNAI, a molecule that controls the replication of ColE1 plasmid, and the cell division inhibitor DicF- RNA. It initiates the decay of RNAs by cutting them internally near their 5'-end. It is able to remove poly(A) tails by an endonucleolytic process. Required to initiate rRNA degradation during both starvation and quality control; ac [...]

Ribonuclease II; Involved in mRNA degradation. Hydrolyzes single-stranded polyribonucleotides processively in the 3' to 5' direction. RNases 2 and R (rnr) contribute to rRNA degradation during starvation, while RNase R and PNPase (pnp) are the major contributors to quality control of rRNA during steady state growth. This RNase is required to decrease expression of RNase PH (rnp) at 42 degrees Celsius during starvation, which in turn represses rRNA degradation. Belongs to the RNR ribonuclease family. RNase II subfamily.

Pantetheine-phosphate adenylyltransferase; Reversibly transfers an adenylyl group from ATP to 4'- phosphopantetheine, yielding dephospho-CoA (dPCoA) and pyrophosphate. CoA is not a substrate for the enzyme ; Belongs to the bacterial CoaD family.

Phosphate ABC transporter ATPase; Part of the ABC transporter complex PstSACB involved in phosphate import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Phosphate importer (TC 3.A.1.7) family.
