Abstract:

The proteolytic activities of crude homogenates from the hepatopancreas of the prawn Macrobrachium rosenbergii were investigated. The caseinolytic and haemoglobin-hydrolysing activities are mainly due to thiol proteases with a minor contribution of trypsin-like activity. The hepatopancreas proteolytic activity is less efficient than trypsin in degrading myofibrillar proteins in intact tissue. The collagenolytic activity in the homogenates differs in substrate specificity from bacterial collagenase. The specificity of these enzymic activities and their relation to mushiness in prawns stored in ice are discussed. © 1989.
