these studies indicate that ( i ) the methionine codon at bp 3879 serves as the initiation codon for the mature e5 protein , ( ii ) changing the charge of the e5 amino-terminus ( from neutral to positive ) does not prevent the association of this hydrophobic polypeptide with cellular membranes , and ( iii ) e5 amino-terminal mutations do not interfere with the ability of this polypeptide to form homodimers .
