title: Three-dimensional structure of Escherichia coli initiator tRNAfMet.
abstract: The crystal structure of Escherichia coli tRNAfMet an initiator transfer RNA, has been determined. While grossly similar to that of the chain-elongating yeast tRNAPhe, there are three major differences. One involves the folding of the anticodon loop; in particular, the position of the constant uridine, U33. This difference was unexpected and may be of functional significance.
