Canavalia brasiliensis seed lectin during germination in the presence of light. The mobilization of the lectin of Canavalia brasiliensis during seed germination, in the presence of light, was studied in comparison with the reserve proteins. Methods employed were determination of soluble protein content, hemagglutinating activity, affinity chromatography on Sephadex G-50 column, and PAGE-SDS. The results showed that the lectin was metabolized later than the reserve proteins suggesting that it may have a special function other than a simple reserve protein.
