Ribose phosphate pyrophosphokinase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P); Belongs to the ribose-phosphate pyrophosphokinase family. Class III (archaeal) subfamily.

RNA 3' terminal phosphate cyclase (RNA 3' phosphate cyclase) (RNA cyclase) (rtcA); Catalyzes the conversion of 3'-phosphate to a 2',3'-cyclic phosphodiester at the end of RNA. The mechanism of action of the enzyme occurs in 3 steps: (A) adenylation of the enzyme by ATP; (B) transfer of adenylate to an RNA-N3'P to produce RNA-N3'PP5'A; (C) and attack of the adjacent 2'-hydroxyl on the 3'-phosphorus in the diester linkage to produce the cyclic end product. The biological role of this enzyme is unknown but it is likely to function in some aspects of cellular RNA processing (By similarity).

N2,N2 dimethylguanosine tRNA methyltransferase; Dimethylates a single guanine residue at position 26 of a number of tRNAs using S-adenosyl-L-methionine as donor of the methyl groups; Belongs to the class I-like SAM-binding methyltransferase superfamily. Trm1 family.

GTP-binding protein; Uncategorized.

Protein L-isoaspartate methyltransferase; Protein modification.

Hypothetical protein.

Conserved hypothetical protein; High hit: PAB1716.

Hypothetical protein; Probably involved in the biogenesis of the ribosome.

DNA-directed RNA polymerase, subunit L (rpoL); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
