Ribonuclease PH; Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation.

Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.

DNA-directed 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.

Orotate phosphoribosyltransferase; Catalyzes the transfer of a ribosyl phosphate group from 5- phosphoribose 1-diphosphate to orotate, leading to the formation of orotidine monophosphate (OMP).

Phage integrase.

Hypothetical protein.

T6A_YeaZ: tRNA threonylcarbamoyl adenosine modification protein YeaZ.

Nicotinate (nicotinamide) nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).

tRNA modification GTPase TrmE; Exhibits a very high intrinsic GTPase hydrolysis rate. Involved in the addition of a carboxymethylaminomethyl (cmnm) group at the wobble position (U34) of certain tRNAs, forming tRNA- cmnm(5)s(2)U34; Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. TrmE GTPase family.
