  • Analysis of nectar from leek (Allium porrum) flowers by SDS-PAGE revealed the presence of two major polypeptide bands of 50 kDa and 13 kDa, respectively. Using a combination of agglutination tests, enzyme assays and N-terminal sequencing, the polypeptides have been identified as subunits of alliin lyase (alliinase, EC and mannose-binding lectin, respectively. The latter protein is particularly abundant since it represents about 75% of the total nectar protein. Honey produced by bees… CONTINUE READING
