pubmed:abstractText |
The intrinsic 22 kDa polypeptide associated with photosystem II (psbS protein) was found to be able to bind chlorophyll. Extraction of isolated photosystem II membranes with octyl-thioglucopyranoside, followed by repetitive electrophoresis under partially denaturing conditions gave only one green band. It contained both chlorophyll a and chlorophyll b, exhibited an absorption maximum at 674 nm and a 77 K fluorescence peak at 675 nm. The chlorophyll-protein band contained a single polypeptide of 22 kDa. Based on these results and on previous protein sequence comparisons, it is suggested that the psbS protein is a chlorophyll a/b binding polypeptide and should thus be denoted CP22.
