title: Hydrogen bonding in yeast phenylalanine transfer RNA.
abstract: Further analysis of the three-dimensional electron density map of yeast phenylalanine tRNA is presented. Attention is focused on the several types of unique hydrogen bonding that are found in the molecule and a number of sections of the electron density map are presented. These sections are compared with an electron density map of a dinucleoside phosphate. The bases in the helical stem regions are all involved in Watson-Crick hydrogen bonding interactions with the exception of the guanine-uracil base pair. Several additional tertiary hydrogen bonding interactions are described.
