title: Isolation and properties of elongation factor 1 from Saccharomyces cerevisiae.
abstract: Polypeptide elongation factor 1 was isolated from yeast postribosomal supernatant. The highly purified factor was resolved on Ultrogel AcA-44 into two complementary fractions. One of these fractions contained two different polypeptide chains corresponding to a Ts-like elongation factor EF-1 beta gamma. The other fraction represented the light form of the factor, designated EF-1 alpha, with a molecular weight of approximately 50,000. The obtained results indicate that EF-1 from lower eukaryotes is also composed of three distinct polypeptides.
