Abstract:
Nucleotide sequence analysis of cDNA clones coding for field bean legumin precursor polypeptides revealed two different types, called A and B. Although homologous, both types differ in several sequence characteristics. Comparison with similar data from soybean and recent findings from pea leads to the following conclusions: (i) the two types of legumin genes described represent two subfamilies, A and B, which are probably of widespread occurrence; (ii) legumin genes or subunits can best be placed in either subfamily A or B by sequence homology, in addition B‐type subunits contain generally fewer (or none at all in V. faba ) Met residues as compared to A‐type subunits; (iii) members of one subfamily from different species are more homologous than members of either subfamily within a species, therefore the two subfamilies must have arisen long before speciation of the genera Glycine, Pisum and Vicia ; (iv) during speciation members of the B‐subfamily diverged significantly more than members of the A‐subfamily.
