One of my professors mentioned something about the e-site (the exit site for the t-RNA) on a eukaryotic ribosome. There was a student in the class who objected, saying that there is no e-site on eukaryotic ribosomes; it only exists on prokaryotic ribosomes. I've tried to find some reliable source to figure out who's right, but to date the only thing I've found is an obscure sentence in a wikipedia article, which doesn't look all that official.
Is there indeed an e-site on the eukaryotic ribosome?
