Abstract

Filaments associated with chloroplasts in cytoplasmic homogenates of the algae Coleochaete scutata and Mougeotia sp. bind rabbit skeletal muscle heavy meromyosin (HMM) to form arrowhead complexes that could be dissociated with ATP. This result suggests that the filaments are actin which may be involved in the characteristic chloroplast movements exhibited by these algae.

摘要

在藻类胶毛藻和双星藻的细胞质匀浆中与叶绿体相连的丝状体能够将兔骨骼肌重酶解肌球蛋白（HMM）结合形成箭头复合物，该复合物可以与 ATP 解离。这一结果表明这些丝状体可能是肌动蛋白，它可能参与了这些藻类表现出的特征性叶绿体运动。
