SYNOPSIS. One of the major changes that occurs during the maturation of oocytes is the accumulation of yolk protein, or vitellin (Vn). To better understand how this process is regulated, we characterized the Vn of the ridgeback shrimp, Sicyonia ingentis (Penaeoidea). This Vn is a 322 kDa molecule composed of three subunits. Using purified Vn, we developed an anti-Vn antiserum and used it to cha...
The present study describes the activity and some characteristics of proteinases in the hepatopancreas of red shrimp Pleoticus muelleri during the different stages of the molting cycle. Proteolytic activity was highest between pH 7.5 and 8. The hepatopancreatic protein content in the premolt stage was higher than in the other stages of the molting cycle (P<0.05). No significant differences were...
