Abstract

The soluble fraction of rat testis homogenates is rich in enzymes catalysing the phosphorylation by ATP of many different proteins. The phosphorylation of certain histones, and also of a homogeneous basic protein from guinea-pig seminal-vesicle secretion, is markedly enhanced by 3':5'-cyclic AMP. Various factors affecting these reactions as catalysed by partially purified testicular enzyme preparations are described, and their possible physiological significance is discussed.

摘要

大鼠睾丸匀浆的可溶部分富含催化多种不同蛋白质由ATP进行磷酸化的酶。3':5'-环磷酸腺苷能显著增强某些组蛋白以及豚鼠精囊分泌物中一种均一碱性蛋白的磷酸化。文中描述了部分纯化的睾丸酶制剂催化这些反应时的各种影响因素,并讨论了它们可能的生理意义。
