The trehalase of the house cricket Acheta domesticus L. (Orthoptera: Gryllidae)

1993

Teo, L.H. | Woodring, J.P.

The optimal pH of the trehalase from the gut of the house cricket was 4.8-5.2 and the activation energy was 13,500 cal/mol. The 50% inactivation time for trehalase at 50 degrees was 110 min and the 50% inhibition concentration for mercuric chloride was 455 micromolar. The caecal tissues were the most important source of gut trehalase but the foregut contents had the highest activity of trehalase. After 5 days of starvation, the total trehalase activity fell by 61%.
