Superoxide dismutase; Destroys radicals which are normally produced within the cells and which are toxic to biological systems. Belongs to the Cu-Zn superoxide dismutase family.

Catalase; PFAM: manganese containing catalase; KEGG: sec:SC1727 putative catalase.

LSU ribosomal protein L13P; This protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly.

Thiol peroxidase (atypical 2-Cys peroxiredoxin); Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides; Belongs to the peroxiredoxin family. Tpx subfamily.

PFAM: ribosomal protein L17; KEGG: sdy:SDY_3470 50S ribosomal subunit protein L17.

Chaperone protein DnaJ; 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 interactions between DnaJ, D [...]

Protein of unknown function UPF0054; Single strand-specific metallo-endoribonuclease involved in late-stage 70S ribosome quality control and in maturation of the 3' terminus of the 16S rRNA.

LSU ribosomal protein L15P; Binds to the 23S rRNA; Belongs to the universal ribosomal protein uL15 family.

LSU ribosomal protein L3P; One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit.
