psb27

Comments [?]

Function	Plays a role in the repair and/or biogenesis of the calcium-manganese-oxide cluster on the lumenal face of the thylakoid membrane. Its presence in a photosystem II (PSII) preparation prevents binding of some small extrinsic subunits and thus assembly of calcium-manganese-oxide cluster.
Subunit	Monomer. Forms a complex with a monomeric, partially assembled PSII. This is probably the complex in which D1 is assembled and/or replaced.
Subcellular location	Cellular thylakoid membrane; Lipid-anchor; Lumenal side. Note=Associated with PSII on the lumenal side of the thylakoid membrane.
Similarity	Belongs to the Psb27 family.
