Comparison of Glycosylated and Deglycosylated Vitellins from Four Species of Weevil (coleoptera: Curculionidae)

l. The vitellins or yolk proteins of four species of weevil (Coleoptera: Curculionidae) consist of two size classes with molecular weights of 150-170 and 4247 kilo daltons (kDa). 2. The ho11 weevil, Anrhonomus grandis, has one large vitellin while Smicronyx fulvus, S. sordidus, and Cylindrocopturus adpersus each have two large vitellins. 3. All four weevils have a single small vitellin whose size differs with genera. 4. In all four species both large and small vitellins contain N-linked glycosyl groups. 5. Enzymatic removal of the N-linked glycosyl chains lowers the molecular weight of the vitellins 9-17%.
