Abstract
IT is generally considered that the major globulins of dicotyledons and the prolamins and glutelins of monocotyledons are reserve proteins, that is, they are digested enzymatically on germination, whereupon the amino-acids and peptides are made available for protein synthesis1. Actually, all the protein in the storage organ of the seed eventually disappears, as does the organ itself. But the label of reserve protein has been put on those proteins, small in number, which comprise a relatively large percentage of the total protein, which change early in germination, and which possess no obvious biological activity. Reserve proteins would be expected to have a characteristic pattern of metabolism on germination; ultracentrifuge patterns of protein extracts of pea-seeds at various stages of germination showed more rapid disappearance of the globulins2, but this technique is not sufficiently discriminating to identify specific proteins with the pattern of change.
