Three isotrypsins from digestive gland of Penaeus vannamei were purified and characterized by molecular, biochemical and kinetic parameters. Purified isotrypsins A, B, and C are glycoproteins with molecular masses between 30.2 and 32.9 kDa, and, therefore similar to other trypsins. The isoelectric points are anionic and different among the three(More)
An immunological approach was used to elucidate whether trypsin is synthesized and stored as trypsinogen in the midgut gland of the shrimp Litopenaeus vannamei. Two peptides were constructed using sequences deduced from known shrimp genes: trypsinogen activation peptide and an internal sequence. These peptides were used as haptens to elicit antibodies in(More)
