[Objective] To investigate the production of adenosine modified with N~6-(Δ2-isopentenyl) and 2-thiomethyl groups from marine-derived Streptomyces xinghaiensis NRRL B24674~T. [Methods] Bioinformatics analysis was carried out to search the genome sequence of S. xinghaiensis NRRL B24674~T and the secondary metabolites were purified by silica gel column chromatography, gel chromatography and high-performance liquid chromatography, and the chemical structure was elucidated by nuclear magnetic resonance(NMR) and...

t RNA的转录后修饰几乎存在于包括古生菌、细菌和真核生物在内的所有生物当中[1]。有趣的是,生物体内存在大量用于t RNA核苷酸的修饰酶[2],从而形成多样的t RNA结构。目前为止,从t RNA中鉴定了100多个被修饰的核苷酸结构(http://medstat.med.utah.edu/RNAmods),例如4-硫尿核苷?
