Protein

Photosystem II reaction center protein Z

Gene

psbZ

Organism
Thermosynechococcus elongatus (strain BP-1)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Controls the interaction of photosystem II (PSII) cores with the light-harvesting antenna. May also aid in binding of PsbK, Ycf12 and the oxygen-evolving complex to PSII, at least in vitro. PSII is a light-driven water plastoquinone oxidoreductase, using light energy to abstract electrons from H2O, generating a proton gradient subsequently used for ATP formation.UniRule annotation4 Publications

Cofactori

Note: PSII binds multiple chlorophylls, carotenoids and specific lipids.11 Publications

Disruption phenotypei

Cells grow normally under all light regimes tested; it is dispensable for photoautotrophic growth. The deletion strain is more tolerant to photoinhibition, while isolated PSII complex contains less PsbK and Ycf12 than wild-type and also has reduced oxygen-evolving capacity.1 Publication

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.
