Abstract
A Y-base derivative was isolated from rat liver tRNAPhe and its structure was assigned to be alpha-(carboxyamino)-beta-hydroxy-4,9-dihydro-4,6-dimethyl-9-oxo-1H-imidazol[1,2-a]purine-7-butyric acid dimethyl ester (hydroxy-Y), based on the results of mass spectrometry and chemical degradation. This modified base seems to be the major fluorescent component of rat liver tRNAPhe; the peroxy-Y base previously isolated from rat liver tRNAPhe and characterized by Nakanishi and his coworkers (1,2) was not present in our preparation.Entities:
