Chaperone protein DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.

GreA/GreB family elongation factor; Necessary for efficient RNA polymerase transcription elongation past template-encoded arresting sites. The arresting sites in DNA have the property of trapping a certain fraction of elongating RNA polymerases that pass through, resulting in locked ternary complexes. Cleavage of the nascent transcript by cleavage factors such as GreA or GreB allows the resumption of elongation from the new 3'terminus. GreA releases sequences of 2 to 3 nucleotides.

Peptide methionine sulfoxide reductase; Has an important function as a repair enzyme for proteins that have been inactivated by oxidation. Catalyzes the reversible oxidation-reduction of methionine sulfoxide in proteins to methionine.

DNA-directed DNA polymerase; Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII.

Queuine tRNA-ribosyltransferase; Catalyzes the base-exchange of a guanine (G) residue with the queuine precursor 7-aminomethyl-7-deazaguanine (PreQ1) at position 34 (anticodon wobble position) in tRNAs with GU(N) anticodons (tRNA-Asp, - Asn, -His and -Tyr). Catalysis occurs through a double-displacement mechanism. The nucleophile active site attacks the C1' of nucleotide 34 to detach the guanine base from the RNA, forming a covalent enzyme-RNA intermediate. The proton acceptor active site deprotonates the incoming PreQ1, allowing a nucleophilic attack on the C1' of the ribose to form t [...]

Peptidase S1 and S6 chymotrypsin/Hap; COGs: COG0265 Trypsin-like serine protease typically periplasmic contain C-terminal PDZ domain; InterPro IPR001478:IPR001254:IPR009003:IPR001940; KEGG: bcv:Bcav_3234 2-alkenal reductase; PFAM: peptidase S1 and S6 chymotrypsin/Hap; PDZ/DHR/GLGF domain protein; SMART: PDZ/DHR/GLGF domain protein; SPTR: C5C0T2 2-alkenal reductase; PFAM: Trypsin; PDZ domain (Also known as DHR or GLGF).

Peptidylprolyl isomerase; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides; Belongs to the cyclophilin-type PPIase family.

Ribosome-binding factor A; One of several proteins that assist in the late maturation steps of the functional core of the 30S ribosomal subunit. Associates with free 30S ribosomal subunits (but not with 30S subunits that are part of 70S ribosomes or polysomes). Required for efficient processing of 16S rRNA. May interact with the 5'-terminal helix region of 16S rRNA.

Fmu (Sun) domain protein; COGs: COG0144 tRNA and rRNA cytosine-C5-methylase; InterPro IPR006027:IPR001678; KEGG: jde:Jden_1312 Fmu (Sun) domain protein; PFAM: Fmu (Sun) domain protein; NusB/RsmB/TIM44; SPTR: D0WMY6 Ribosomal RNA small subunit methyltransferase B; PFAM: NOL1/NOP2/sun family; NusB family; TIGRFAM: ribosomal RNA small subunit methyltransferase RsmB; Belongs to the class I-like SAM-binding methyltransferase superfamily. RsmB/NOP family.
