Methylation of elongation factor 1 alpha from the fungus Mucor.

Abstract
A basic protein from the dimorphic fungus M. racemosus, highly methylated, is protein synthesis elongation factor 1.alpha.. This protein is the most abundant protein in hyphal cells but is less abundant in yeast cells. It is posttranslationally methylated with the formation of mono-, di-, and trimethyllysine at as many as 16 sites. Nearly 20% of the 44 lysine residues of elongation factor 1.alpha. from mycelia are modified while those from sporangiospores are virtually unmethylated.
