Etioplasts capable of incorporating (14)C-leucine into protein have been isolated from dark-grown pea and wheat plants. The requirements for leucine incorporation for etioplasts were similar to those for chloroplasts. An ATP-generating system, Mg(2+), and GTP were required. The amino-acid-incorporation activity of etioplasts from wheat was comparable to that of chloroplasts on an RNA basis, whereas the activity of pea etioplasts was about 50% of the activity of pea chloroplasts. The incorporation of leucine into protein by etioplasts and chloroplasts from pea and wheat was inhibited by chloramphenicol, and to a slight extent by cycloheximide.
已从黑暗中生长的豌豆和小麦植株中分离出能够将(14)C-亮氨酸掺入蛋白质的黄化质体。黄化质体掺入亮氨酸的条件与叶绿体相似。需要一个ATP生成系统、Mg(2+)和GTP。从小麦黄化质体的RNA基础来看,其氨基酸掺入活性与叶绿体相当,而豌豆黄化质体的活性约为豌豆叶绿体活性的50%。豌豆和小麦的黄化质体及叶绿体将亮氨酸掺入蛋白质的过程受到氯霉素的抑制,并在一定程度上受到环己酰亚胺的抑制。
