Abstract*
Our present investigation reports the qualitative analysis of esterases and their classification from the silk gland of mulberry silk worm (Bombyx mori L). The qualitative analysis of esterases was carried out through 7.5% of native Polyacrylamide Gel Electrophoresis (PAGE). The study included the inhibitor sensitivity of the enzymes towards organophosphate compounds (OP) such as paraxon, eserine and pCMB which were also used for the classification of individual zones of esterases in silk worm. The results revealed that the esterase activity of was inhibited by the paraxon and eserine (Physostigmine) and there was no inhibition in the presence of pCMB. Hence, these esterases were classified as Carboxylesterases (CE).
