摘要

突变体和分离分子结构的研究表明,两种血红素蛋白-细胞色素c (552, Euglena)和细胞色素b (561, Euglena) -在叶绿体中具有功能定位。另外两种细胞色素c型(556,Euglena)和细胞色素a型(605,Euglena)似乎与呼吸系统有关。叶绿体发育各阶段的动力学分析数据表明,叶绿体中的功能单元包含恒定比例的叶绿素和光合细胞色素(每个细胞色素350个叶绿素分子)。

Iron-containing proteins in euglena

Studies mutants and isolated molecular structures demonstrate that the two haem proteins—cytochrome c (552, Euglena) and cytiochrome b (561, Euglena)—are functionally localized in the choloplasts. Two others—cytochrome type c (556, Euglena) and cytochrome type a (605, Euglena)—appear to be associated with the respiratory system.

Data obatined by kinetic analyses of composition during various phases of chloroplast development indicate that functional units in the chlotoplast are built containing constant ratios of chlorophyll to the photosynthetic cytochromes (350 chlorophyll molecules for each cytochrome).
