| pubmed-article:1899025 | pubmed:abstractText | 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 role of this protein in O2 evolution remains to be elucidated. Here we describe the construction of a mutant of the cyanobacterium Synechocystis sp. PCC6803 in which the entire gene encoding MSP has been deleted. Northern and immunoblot analyses indicate that other PSII proteins are expressed and accumulated, despite the absence of MSP. Fluorescence emission spectra at 77 K indicate PSII assembles in the mutant, but that the binding of MSP is required for the normal fluorescence characteristics of the PSII complex, and suggest a specific interaction between MSP and CP47. Fluorescence induction measurements indicate a reduced rate of forward electron transport to the primary electron donor, P680, in the mutant. It is concluded that in contrast to previous reports, MSP is not required for the assembly of active PSII complexes nor is it essential for H2O-splitting activity in vivo. | lld:pubmed |
