| Research Abstract |
Mechanism of assembly of photosystem II complex (PSII) has been investigated focusing on the role of extrinsic proteins in the assembly process of PSII. Psb28 is a newly identified extrinsic protein bound to PSII but its function was unknown. In this study, we analyzed properties of PSII in a disruption mutant of psb28 gene of cyanobacterium. It was found that, in the psb28 mutant, PSII assembly intermediates were accumulated and that a repair process of PSII was significantly inhibited. These results suggest that Psb28 plays an important role in the repair process of PSII.
