中文摘要 | Thylakoid membranes were isolated and purified from gametophyte of Porphyra haitanesis by sucrose density gradient ultracentrifugation. After P. haitanesis gametophyte thylakoid membranes were solubilized with sodium dodecyl sulfate (SDS), the highly pure and active photosystem (PS) II complex was isolated and characterized by the room absorption and fluorescence emission spectra, DCIP (2, 6-Dichloroindophenol) reduction and oxygen- evolving rates. The PS II complex from P. haitanesis had the characteristic absorption peaks of chlorophyll (Chl) a (436 and 676 urn) and typical fluorescence emission peak at 685 nm (Ex = 436 nm). Acquired PS II complex exhibited high oxygen evolution (879 mu mol O-2. mg(-1) Chl. h(-1)) in the present of 2.5 mM DCIP as an artificial acceptor and was active in photoreduction of DCIP (2, 6- dichloroindophenol) by DPC (1, 5- diphenylcarbazide) at 104 ueq. mg(-1).Chl a. h(-1). Extrinsic proteins of P. haitanesis PS II consisted of 33, 20, 16, 12 kD proteins and cyt c-550 (15 kD), and were different with that of cyanobacteria and higher plants. |
