【 摘 要 】

Heat treatment of a highly active photosystem II preparation (600 μmol O₂. mg Chl⁻¹.h⁻¹) caused the release of several polypeptides. One of the polypeptides was found to bind to a fluphenazine-Sepharose affinity column in a calcium-dependent manner. The purified polypeptide was able to stimulate calmodulindepleted 3',5'-cyclic nucleotide phosphodiesterase, indicating a possible similarity with calmodulin.
