中文摘要: |
金属硫蛋白(Metallothionein,MT)是一种低分子量的蛋白质,广泛存在于大多数生物体内,在参与必需金属元素调节和非必需金属元素的解毒等方面具有重要作用。介绍了MT的结构与功能,对贝类MT的诱导机制、解毒机理、降解与金属排除进行概述,探讨了MT诱导合成过程中的一些主要影响因素。由于贝类MT能够通过多途径诱导,而且存在众多的环境因素和自身生理因素的影响,MT的变化规律往往出现较大的波动性。因此,今后的研究重点会是贝类MT作为污染监测指示物的研究、重金属诱导MT数学模型的构建以及贝类MT产品的开发等方面。 |
英文摘要: |
Metallothionein(MT),a small protein,is widely found in most living organisms. It takes an important role in essential metals regulation and non-essential metals detoxification. This paper briefly describes the structure and functions of MT,and MT induction mechanisms,detoxification processes, degradation and metal-exclusion inmollusca; some major factors are discussed in the process of MT induction. For mollusca MT could be induced variously,and there are a large number of environmental factors and physiological factors internal,the concentration of MT often fluctuate remarkably. Therefore,future research will be focused on mollusca MT as a monitoring indicator of pollutions,MT mathematical models construction under the induction of heavy metals and mollusca MT products development. |
