A rapid technique for quantitative separation of ribose-methylated nucleosides from base-methylated and non-methylated nucleosides by chromatography on DEAE-cellulose paper in the presence of borate is described. The method has been used as an assay for tRNA ribose methylases from yeast, using under methylated Escherichia coli tRNA as substrate. The main product formed with a partly purified yeast enzyme was characterized as 2'-O-methylcytidine.
本文描述了一种在硼酸盐存在下,通过DEAE - 纤维素纸色谱法从碱基甲基化和未甲基化的核苷中快速定量分离核糖甲基化核苷的技术。该方法已被用作检测酵母中tRNA核糖甲基化酶的分析方法,使用甲基化不足的大肠杆菌tRNA作为底物。用部分纯化的酵母酶形成的主要产物被鉴定为2'-O-甲基胞苷。
