Abstract
Tryptic-peptide profiles and amino acid sequencing of purified pea (Pisum sativum L.) vicilin subunits were used to show that their sequences were interrelated. Comparison with the nucleotide sequence of a cloned vicilin complementary DNA (mRNA) showed that all vicilin subunits could be derived from 50 000-Mr precursors containing up to two sites for post-translational proteolytic cleavage, and allowed these subunits to be located relative to the precursor.
