In vivo biosynthesis of a stage-specific cuticle glycoprotein during early metamorphosis of the medfly Ceratitis capitata
Cuticle proteins of an insect pest, the Medfly Ceratitis capitata, were resolved in polyacrylamide gels and partially characterized. The pupal cuticle was found to be different from cuticles of other insects since more than 80% w w of the protein is a single mannose-containing polypeptide (PCG-100)....
