SOME PROPERTIES OF TREHALASE FROM CHALCOPHORA VERGINICA (COLEOPTERA: BUPRESTIDAE) AND POEKILOCERU PICTUS (ORTHOPTERA: ACRIDIDIAE)

摘要

Assay of trehalase activity in adults of Chalcophora verginica and Poekilocerus pictus revealed Km value 3.17 x 106 M and 3.56 x 10-6 M; optimum pH 5.8 and 5.6, respectively. Maximum enzyme activity was recorded at 50 oC. Testing of enzyme activity with chemical substances showed 0.1 M NaCl as activator (Cl-).
