UniProt functional annotation for P72780

UniProt code: P72780.

Organism: Synechocystis sp. (strain PCC 6803 / Kazusa).
Taxonomy: Bacteria; Cyanobacteria; Synechococcales; Merismopediaceae; Synechocystis; unclassified Synechocystis.
 
Function: A putative protease, its function overlaps that of the related putative proteases HhoB and HtrA. {ECO:0000269|PubMed:16912048}.
 
Subcellular location: Periplasm {ECO:0000305}.
Induction: Slight induction by UV-B light. {ECO:0000269|PubMed:17208194}.
Disruption phenotype: No effect in a single knockout, but growth is inhibited at high light (120 umol photons/m(2)/s) or at elevated temperature in a triple protease knockout mutant (hhoA, hhoB and htrA). Triple mutants are not phototactic. No effect on the PSII repair cycle, even in the triple protease knockout strain. {ECO:0000269|PubMed:16912048, ECO:0000269|PubMed:17208194}.
Similarity: Belongs to the peptidase S1C family. {ECO:0000305}.
