Comparative studies on cuticular and blood phenol oxidases of a shore crabOcpod platytarsis

Abstract
The properties of blood and cuticular phenol oxidases of Ocypod platytarsis have been studied. The blood phenol oxidase exists in the form of proenzyme. The blood phenol oxidase differs from cuticular phenol oxidase with reference to substrate specificity, pH optima, electrophoretic mobility and effect of chemicals. Based on the property, the possible functions of the phenol oxidases from blood and cuticle have been suggested.
