Catalase-peroxidase; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity; Belongs to the peroxidase family. Peroxidase/catalase subfamily.

Glutaredoxin 1; Similar to Escherichia coli, and Shigella flexneri glutaredoxin 1 GrxA or Grx or b0849 or sf0802 SWALL:GLR1_ECOLI (SWALL:P00277) (85 aa) fasta scores: E(): 6e-21, 69.88% id in 83 aa.

DNA protection during starvation protein; During stationary phase, binds the chromosome non- specifically, forming a highly ordered and stable dps-DNA co-crystal within which chromosomal DNA is condensed and protected from diverse damages. It protects DNA from oxidative damage by sequestering intracellular Fe(2+) ion and storing it in the form of Fe(3+) oxyhydroxide mineral, which can be released after reduction. One hydrogen peroxide oxidizes two Fe(2+) ions, which prevents hydroxyl radical production by the Fenton reaction.

Bifunctional PutA protein [includes: proline dehydrogenase; Oxidizes proline to glutamate for use as a carbon and nitrogen source; Belongs to the aldehyde dehydrogenase family. In the N-terminal section; belongs to the proline dehydrogenase family.

Alkyl hydroperoxide reductase C22 protein; 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. AhpC/Prx1 subfamily.

Putative acyl-CoA synthetase; Similar to Yersinia pestis putative acetyltransferase ypo3272 SWALL:Q8ZBW2 (EMBL:AJ414156) (880 aa) fasta scores: E(): 0, 79.56% id in 881 aa, and to Escherichia coli hypothetical protein yfiq or b2584 SWALL:YFIQ_ECOLI (SWALL:P76594) (886 aa) fasta scores: E(): 0, 76.84% id in 881 aa.

ATP-dependent Clp protease proteolytic subunit; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins. Belongs to the peptidase S14 family.

Heat shock protein; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins, in association with DnaK and GrpE. It is the nucleotide exchange factor for DnaK and may function as a thermosensor. 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-depen [...]

Similar to Salmonella typhimurium putative universal stress protein ydaa or stm1661 SWALL:Q8ZP84 (EMBL:AE008773) (315 aa) fasta scores: E(): 3e-104, 81.58% id in 315 aa, and to Escherichia coli, Escherichia coli O6, Escherichia coli O157:H7, and Shigella flexneri protein ydaa or b1333 or c1806 or z2435 or ecs1914 or sf1837 SWALL:AAN43399 (EMBL:AE000231) (325 aa) fasta scores: E(): 3.6e-102, 80% id in 315 aa.
