Metalloprotein, YbeY/UPF0054 family; Single strand-specific metallo-endoribonuclease involved in late-stage 70S ribosome quality control and in maturation of the 3' terminus of the 16S rRNA.

Thymidine phosphorylase; PFAM: Glycosyl transferase family, a/b domain; Pyrimidine nucleoside phosphorylase C-terminal domain; Glycosyl transferase family, helical bundle domain; TIGRFAM: pyrimidine-nucleoside phosphorylase.

GTP-binding protein Era; An essential GTPase that binds both GDP and GTP, with rapid nucleotide exchange. Plays a role in 16S rRNA processing and 30S ribosomal subunit biogenesis and possibly also in cell cycle regulation and energy metabolism.

Phosphate starvation-inducible protein PhoH, predicted ATPase; PFAM: Hom_end-associated Hint; PhoH-like protein.

Putative metal-dependent protease of the PAD1/JAB1 superfamily; PFAM: Mov34/MPN/PAD-1 family.

RNA methyltransferase, RsmE family; Specifically methylates the N3 position of the uracil ring of uridine 1498 (m3U1498) in 16S rRNA. Acts on the fully assembled 30S ribosomal subunit.

DnaJ-class molecular chaperone with C-terminal Zn finger domain; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of A [...]

Cysteine synthase; PFAM: Pyridoxal-phosphate dependent enzyme; TIGRFAM: cysteine synthases.
