Abstract
Osmotic regulation in the flagellate Ochromonas malhamensis Pringsheim is mainly mediated by changes in the pool size of alpha-galactosyl-(1 --> 1)-glycerol (isofloridoside). Isofloridoside phosphate synthase, a regulated key enzyme responsible for the formation of isofloridoside phosphate, appears to exist as an inactive proenzyme which can be activated by incubation of crude cell extracts with endogenous or exogenous proteases.
摘要
在鞭毛生物眼虫（Ochromonas malhamensis Pringsheim）中，渗透调节主要是通过α-半乳糖基-(1 --> 1)-甘油（异佛尔酮糖苷）池大小的变化来介导的。异佛尔酮糖苷磷酸合酶是一种受调控的关键酶，负责异佛尔酮糖苷磷酸的形成，它似乎以无活性的酶原形式存在，可以通过在粗细胞提取物中孵育内源性或外源性蛋白酶来激活。
