Amino acid sequence of the smaller subunit of conglutin gamma, a storage globulin of Lupinus angustifolius.

The amino acid sequence of the smaller subunit of conglutin gamma, the simplest of the three globulins from the seeds of Lupinus angustifolius cv. Uniwhite, has been determined. The subunit was homogeneous and contained 154 amino acid residues, including five sulphur-containing amino acids--a considerably higher content than is found in most other legume storage proteins. There was no indication of the complexity experienced in studies of many other legume storage proteins. This is perhaps the first sequence of a subunit of a legume storage protein to be determined.
