The N-terminal amino acid sequence of the beta-subunit of the legumin-like protein from seeds of Ginkgo biloba.

The sequence of the first 52 amino acids at the N-terminus of the beta-subunit of a legumin-like protein from seeds of the gymnosperm Ginkgo biloba were determined by automated sequencing and DABITC/PITC microsequence analyses of peptides derived from the protein by enzymatic digestions and chemical cleavage with CNBr. The protein from Ginkgo exhibits sequence homologies (32-49% identities) with the 11S globulins and legume-like proteins from seeds of various angiosperm monocotyledons and dicotyledons.
