Plasmin and plasminogen were detected in individual camel milks using
a fluorogenic substrate. The results obtained suggested that camel mil
k may contain less plasmin and plasminogen in early lactation than nor
mally found in cow milk. The proteolytic activity of camel plasmin on
camel casein was comparable to the proteolytic activity of bovine plas
min on this casein, suggesting that camel caseins A and B are homologo
us to bovine alpha- and beta-caseins.
