title: Isolation and characterization of a low-molecular weight seed protein from Ricinus communis.
abstract: A seed protein with an apparent molecular weight of 5000 has been isolated and purified from Ricinus communis. This protein has a very high content of glutamine and an unusual ultraviolet absorption spectrum. The amino-terminal sequence of 22 residues determined by automatic Edman degradation is: NH2-Pro-Ser-Gln-Gln-Gly-Cys-Cys-Gly-Gln-Ile-Gln-Glu-Gln-Gln-Asn-Leu-Arg-Gln-Cys-Gln-Glu-Tyr-.
