Ribosome small subunit-dependent GTPase A; One of several proteins that assist in the late maturation steps of the functional core of the 30S ribosomal subunit. Helps release RbfA from mature subunits. May play a role in the assembly of ribosomal proteins into the subunit. Circularly permuted GTPase that catalyzes slow GTP hydrolysis, GTPase activity is stimulated by the 30S ribosomal subunit; Belongs to the TRAFAC class YlqF/YawG GTPase family. RsgA subfamily.

PFAM: peptidase M48, Ste24p; KEGG: rfr:Rfer_1411 STE24 endopeptidase.

KEGG: rfr:Rfer_2106 ATP-dependent helicase HrpA; TIGRFAM: ATP-dependent helicase HrpA; PFAM: helicase domain protein; helicase-associated domain protein; protein of unknown function DUF1605; SMART: AAA ATPase; DEAD-like helicases-like.

Metal dependent phosphohydrolase; Catalyzes the addition and repair of the essential 3'- terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate. Also shows phosphatase, 2'-nucleotidase and 2',3'-cyclic phosphodiesterase activities. These phosphohydrolase activities are probably involved in the repair of the tRNA 3'-CCA terminus degraded by intracellular RNases.

PFAM: helicase domain protein; DEAD/DEAH box helicase domain protein; SMART: DEAD-like helicases-like; KEGG: rfr:Rfer_1413 DEAD/DEAH box helicase-like; Belongs to the DEAD box helicase family.

DNA polymerase III, epsilon subunit; DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. The epsilon subunit contain the editing function and is a proofreading 3'- 5' exonuclease.

RNAse III; Digests double-stranded RNA. Involved in the processing of primary rRNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Processes some mRNAs, and tRNAs when they are encoded in the rRNA operon. Processes pre-crRNA and tracrRNA of type II CRISPR loci if present in the organism.

poly(A) polymerase; Adds poly(A) tail to the 3' end of many RNAs, which usually targets these RNAs for decay. Plays a significant role in the global control of gene expression, through influencing the rate of transcript degradation, and in the general RNA quality control. Belongs to the tRNA nucleotidyltransferase/poly(A) polymerase family.

DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
