We have determined the nucleotide sequences of the psbE and psbF genes, which encode the alpha and beta subunits, respectively, of cytochrome b-559, from the chloroplast genome of the green alga Chlamydomonas reinhardtii. In contrast to other organisms psbE is not co-transcribed with psbF. The primary structures of the gene products are very similar to the equivalent proteins in cyanobacteria and plants. Each subunit contains a single histidine residue that is thought to ligate haem. Upstream of the psbE gene, a trnM gene is located which encodes an elongator tRNA(Met) molecule.
我们已经测定了莱茵衣藻叶绿体基因组中分别编码细胞色素b-559的α和β亚基的psbE和psbF基因的核苷酸序列。与其他生物不同，psbE不与psbF共转录。基因产物的一级结构与蓝细菌和植物中的相应蛋白质非常相似。每个亚基都含有一个单一的组氨酸残基，据认为该残基与血红素结合。在psbE基因的上游，有一个trnM基因，它编码一个延伸因子tRNA(Met)分子。
