Psb27 structure from SynechocystisPsb27 structure from Synechocystis

Structural highlights

2knd is a 1 chain structure with sequence from Synechocystis sp. PCC 6803. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:Solution NMR
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

PSB27_SYNY3 Plays a role in the repair and/or biogenesis of the calcium-manganese-oxide cluster on the lumenal face of the thylakoid membrane. Photosystem II (PSII) complexes containing this protein are monomeric, are assembly intermediates lacking the calcium-manganese-oxide cluster and miss some of the lumenal subunits. Probably blocks binding of some of the small lumenal subunits.[1] [2] [3] [4] [5]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
