Disruption phenotypei

No effect in a single knockout, but growth is inhibited at high light (120 µmol photons/m2/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.2 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
