Amino acid sequence of the 26 kDa subunit of legumin-type seed storage protein of common buckwheat (Fagopyrum esculentum Moench): molecular characterization and phylogenetic analysis.
The paper describes the amino acid sequence of a 26 kDa basic subunit of 13S globulin of common buckwheat (Fagopyrum esculentum Moench). The protein has 93 and 75% sequence homology with 11S globulin of Coffea arabica and beta subunit of 11S globulin of Cucurbita pepo respectively. The subunit has the "globally conserved" N-terminal sequence consisting of Gly-Ile-Asp-Glu and the cysteine at P7' from the proteolytic processing site. A conserved 7 residue domain of Pro-His-Trp-Asn-Ile-Asn-Ala, characteristic of basic subunits of legumins from non-leguminous angiosperms, is also present in this protein. A distinguishing features of this subunit is the relatively high level of lysine and methionine.
