The protein composition of polyribosome-bound mRNAs from the embryonic axis of germinating kidney bean seeds, isolated by an improved procedure including treatment with EDTA, low concentrations of RNase T/sub 1/, and centrifugation in a linear 15-40% sucrose concentration gradient, was investigated. Electrophoretic analysis of the proteins of purified fragments of mRNP obtained by the method described showed the presence of two to three major polypeptides (molecular weights 50, 38, 32 kilodaltons) and a number of minor ones. It was established that one of the major proteins is associated with the poly(A) sequences of mRNA (50 kilodaltons). The similarity of the protein compositions of polyribosomal mRNAs of kidney bean embryos and other objects studied is discussed.
