具放氧活性的光系统Ⅱ核心复合物的光谱特性和叶绿素蛋白质成分的研究

STUDIES ON SOME SPECTRAL CHARACTERISTICS AND CHLOROPHYLL PROTEIN COMPONENT OF AN OXYGEN-EVOLVING PSII CORE COMPLEX

我们从菠菜叶片分离出一种具有高放氧活性的光系统Ⅱ(PSII)核心复台物.我们对这种PSII核心复合物进行了PSII光化学活性、吸收、荧光光谱特性和叶绿素蛋白质成分的研究.这种PSII核心复合物是一种不含PSI成分,又除去了LHC-Ⅱ的较纯,较小的具有高放氧活性(?)的单位.在文中对PSII反应中心叶绿素的吸收成分和CPa带进行了一些讨论.

A highly active O2-evolving PSII core complex had been isolatedfrom spinach leaves, and its PSII photo chemical activities, characteristics ofabsorption ipectra, fluorescence spectra and chlorophyll protein component hadbeen studied. It was a purer and smaller O2-evolving structural unit deprived of both PSI component and LHC-II.Some subjects such as PSII reaction center Chla absorption component and CPa band have been discussed.
