    • The invention relates to new proteins called alkylcytosine transferases (ACTs) derived from O6-alkylguanine-DNA alkyltransferase, and to substrates for ACTs specifically transferring a label to these ACTs and to fusion proteins comprising these. The substrates according of the invention are substituted cytosines of formula (I) wherein R1 is an aromatic or a heteroaromatic group, or an optionally substituted unsaturated alkyl, cycloalkyl or heterocyclyl group with the double bond connected to OCH2—; R2 is a linker; and L is a label or a plurality of same or different labels. The invention further relates to methods of transferring label L from these substrates of formula (I) to ACTs and ACT fusion proteins. The system of ACT-compound of formula (I) is particularly suitable for double labelling studies together with the known system O6-alkylguanine-DNA alkyltransferase (AGT)-benzylguanines.
    • 本发明涉及从O6-烷基鸟嘌呤-DNA烷基转移酶衍生的称为烷基胞嘧啶转移酶(ACT)的新蛋白质,以及特异性将标记转移至这些ACT的ACT的底物和包含它们的融合蛋白。 根据本发明的底物是其中R 1是芳族或杂芳族基团的式(I)的取代的胞嘧啶或具有与OCH 2连接的双键的任选取代的不饱和烷基,环烷基或杂环基; R2是连接体; L是标签或多个相同或不同的标签。 本发明还涉及将标记L从这些式(I)底物转移到ACT和ACT融合蛋白的方法。 式(I)的ACT-化合物的系统特别适用于已知的系统O6-烷基鸟嘌呤-DNA烷基转移酶(AGT) - 苄基胍的双重标记研究。
