Sensor protein; Two component system regulator.

Sensor protein, ATPase-like:Histidine kinase; ATP + protein L-histidine = ADP + protein N-phospho-L-histidine.

ATP-binding region, ATPase-like:Histidine kinase, Histidine kinase A-like precursor; ATP + protein L-histidine = ADP + protein N-phospho-L-histidine.

D-tyrosyl-tRNA(Tyr) deacylase; An aminoacyl-tRNA editing enzyme that deacylates mischarged D-aminoacyl-tRNAs. Also deacylates mischarged glycyl-tRNA(Ala), protecting cells against glycine mischarging by AlaRS. Acts via tRNA- based rather than protein-based catalysis; rejects L-amino acids rather than detecting D-amino acids in the active site. By recycling D- aminoacyl-tRNA to D-amino acids and free tRNA molecules, this enzyme counteracts the toxicity associated with the formation of D-aminoacyl- tRNA entities in vivo and helps enforce protein L-homochirality. Belongs to the DTD family.

Phosphopantetheine adenylyltransferase; Reversibly transfers an adenylyl group from ATP to 4'- phosphopantetheine, yielding dephospho-CoA (dPCoA) and pyrophosphate. Belongs to the bacterial CoaD family.

NADH-quinone oxidoreductase chain G (NADH dehydrogenase I, chain G); NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient. Belongs to the complex I 75 kDa subunit family.
