β-sheet类核酸结合结构域的作用原理

Principle of β-sheet Nucleic Acid Binding Domain

β-sheet类核酸结合域广泛存在于各种DNA特别是RNA结合蛋白中 ,参与生物体的各种基因调控 ,是一种重要的反式作用结构域 ,根据其基本的结构特征 ,可以推测其与多核苷酸链识别结合的作用机理。

β-sheet nucleic acid binding domain is very common in different kinds of DNA and RNA binding proteins.It participates in many gene expressions of the organisms. So, it's a important trans domain. The principle of the recognizing between the domain and the nucleotide strand can be concluded from its basic structural characteristics.
