Abstract
Hydroxylated cytokinin, 2-methylthio-N6-(4-hydroxy-3-methylbut-2-enyl) adenosine, was found in the tRNA of Azotobacter vinelandii. This cytokinin had the trans configuration, unlike the cis configuration reported for that from other bacteria. Culture-condition-dependent changes in the content of this thiocytokinin and a few other thionucleosides in the tRNA of this bacterium have been observed.
摘要
在棕色固氮菌的转运核糖核酸（tRNA）中发现了羟基化细胞分裂素，即2-甲硫基-N6-（4-羟基-3-甲基丁-2-烯基）腺苷。与报道的其他细菌来源的细胞分裂素的顺式构型不同，这种细胞分裂素具有反式构型。已观察到该细菌tRNA中这种硫代细胞分裂素和其他一些硫代核苷的含量随培养条件而变化。
