AUG is the only initiation codon in eukaryotes.
Abstract
An analysis of mutants of the yeast Saccharomyces cerevisiae indicates that AUG is the sole codon capable of initiating translation of iso-1-cytochrome c. This result with yeast and the sequence results of numerous eukaryotic genes indicate that AUG is the only initiation codon in eukaryotes; in contrast, results with Escherichia coli and bacteriophages indicate that both AUG and GUG are initiation codons in prokaryotes. The difference can be explained by the lack of the t6 A hypermodified nucleoside (N-[9-(beta-D-ribofuranosyl)purin-6-ylcarbamoyl]threonine) in prokaryotic initiator tRNA and its presence in eukaryotic initiator tRNA.
