30S ribosomal protein S7; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the head domain of the 30S subunit. Is located at the subunit interface close to the decoding center, probably blocks exit of the E-site tRNA; Belongs to the universal ribosomal protein uS7 family.

50S ribosomal protein L21; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family.

Putative PAS sensor hybrid histidine kinase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative receptor.

RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

Conserved hypothetical protein; Homologs of previously reported genes of unknown function.

Heat shock protein (Hsp40), co-chaperone with DnaK; 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 ATP-dependent [...]

Putative chaperone protein, DnaJ domain; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative factor.

Chaperone DnaJ domain protein, putative heat shock protein; Function of strongly homologous gene; factor.

Conserved hypothetical protein, containing N-terminal fragment of heat shock protein DnaJ; Homologs of previously reported genes of unknown function.
