胞嘧啶脱氨酶家族是核苷酸代谢过程中的一大酶类超家族,它们通过使胞嘧啶突变成尿嘧啶来编辑DNA和/或RNA,从而影响着多种生理功能。在这些胞嘧啶脱氨酶中,APOBEC蛋白(apolipoprote inB ed iting catalytic polypeptide)代表着一个簇生的家族,它的成员都至少有一个特征性的锌结
Cytosine deaminase family is a major enzyme superfamily in the process of nucleotide metabolism. They edit DNA and / or RNA by mutating cytosine into uracil and thus affect various physiological functions. Among these cytosine deaminases, the APOBEC protein represents a cluster of families whose members all have at least one characteristic zinc junction
