Abstract
The modified nucleoside, 7-(4,5-cis-dihydroxy-1-cyclopenten-3-yl-aminomethyl)-7-deazaguanosine, designated as Q, and its derivative, Q*, were found in tRNA's from various organisms, including several mammalian tissues, other animals such as starfish, lingula and hagfish, and wheat germ. Q isolated from rat liver tRNA was found to be identical with E. coli Q by mass spectrometry and thin-layer chromatography. Thus the rare modified nucleoside Q originally isolated from E. coli tRNA, is widely distributed in various organisms. Analysis of the mass spectrum of Q* suggested that it has a different side chain from Q.Entities:
