Deletion mutagenesis in Synechocystis sp. PCC6803 indicates that the Mn-stabilizing protein of photosystem II is not essential for O2 evolution.

Biochemistry - 15 Jan 1991

Burnap R L, Sherman L A

Abstract excerpt

The photosystem II (PSII) reaction center complex coordinates a cluster of Mn atoms that are involved in the accumulation of oxidizing equivalents generated by light-induced charge separations within the intrinsic portion of the PSII complex. A 33-kDa extrinsic protein, termed the Mn-stabilizing protein (MSP), has been implicated in the stabilization of two of the four Mn atoms of the cluster, yet the precise...
