In the green alga Acetabularia mediterranea a light-harvesting chlorophyll a/b.protein complex of 67 000 daltons has been found which contains two polypeptide chains of 21 500 and 23 000 daltons. These two polypeptides were isolated on a preparative scale and were further characterized by several different methods. Both polypeptides proved to be very similar. While their amino acid and sugar compositions as well as their immunochemical properties were almost identical the tryptic peptides and the cyanogen bromide fragments of the two polypeptides revealed minor but significant differences. The 67 000-dalton chlorophyll a/b.protein complex and its two polypeptide components were compared to the light-harvesting chlorophyll a/b.protein of higher plants.
在地中海伞藻中发现了一种分子量为67000道尔顿的捕光叶绿素a/b蛋白复合体，它含有两条分子量分别为21500和23000道尔顿的多肽链。这两条多肽在制备规模上被分离出来，并通过几种不同的方法进一步表征。结果表明，这两条多肽非常相似。虽然它们的氨基酸和糖组成以及免疫化学性质几乎相同，但两条多肽的胰蛋白酶肽段和溴化氰片段显示出微小但显著的差异。将67000道尔顿的叶绿素a/b蛋白复合体及其两个多肽组分与高等植物的捕光叶绿素a/b蛋白进行了比较。
