Abstract

Gossypin and congossypin, major storage proteins of cottonseed, are characterized by sedimentation constants (S20,wof )1 1.0 and 7.6, molecular weights of 240000 and 143000, E:: at 280 nm of 7.6 and 6.0, and UV absorption maxima of 279 and 277 nm, respectively. Both proteins have a fluorescence emission maximum at 325 nm. They have a globular shape, an oligomeric structure with subunits, and a secondary structure consisting mostly of @-pleated and aperiodic structures. The proteins are rich in glutamic acid, arginine, and aspartic acid and relatively low in sulfur amino acids.
