the similarity of the amino acid composition of ef-1 gamma and ef-1 delta and the molar ratio of alpha : beta : gamma : delta in ef-1h of approximately 1:1:0.5:0.5 have led to the conclusion that ef-1 delta is probably a breakdown product of ef-1 gamma , and that the native form of ef-1h probably contains only the alpha , beta , and gamma subunits .
