本文就鱼类同工酶及遗传的控制,多肽构成,有关酶的基因相同性和重复、变异的维持机制,以及将变异作为标志的种群研究等作一概述。催化某一反应的酶,在同一机体里以几种不同分子型的形式存在叫同工酶(Isory-me)。已有人将同工酶技术应用于水产科学研究,这里就研究中有所进展的乳酸脱氢酶为例,在述及包括同工酶基础理论的同时,介绍一下鱼类同工酶研究的一些情况。
This article summarizes the control of fish isoenzymes and inheritance, the composition of polypeptides, the genetic identity and duplication of enzymes, the maintenance mechanism of variation, and the study of population-based mutants. Enzymes that catalyze a reaction exist as isozymes (Isory-me) in several different molecular forms in the same organism. Some people have been using isozyme technology in aquatic scientific research, here on the progress of research in lactate dehydrogenase, for example, including the basic theory of isozymes at the same time, introduce some of the fish isozyme research Happening.
