Organism

Synechocystis sp. (strain PCC 6803 / Kazusa) [Reference proteome] [HAMAP]

Taxonomic identifier

1111708 [NCBI]

Taxonomic lineage

cellular organisms › Bacteria › Cyanobacteria › Oscillatoriophycideae › Chroococcales › Synechocystis › Synechocystis sp. PCC 6803

Protein attributes

Sequence length	379 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Required for the assembly and stabilization of PSII By similarity.
Catalytic activity	Peptidylproline (omega=180) = peptidylproline (omega=0).
Subcellular location	Cellular thylakoid lumen Probable Ref.2.
Sequence similarities	Contains 1 PPIase cyclophilin-type domain.
Sequence caution	The sequence BAA10250.1 differs from that shown. Reason: Erroneous initiation.
