Esterase A4 elevation mechanism in relation to Bombyx (Lepidoptera: Bombycidae) egg diapause development

The esterase A4 (Ease A4) has been obtained from Shi 108 Bombyx diapause eggs using isoelectric focusing. In the chilling of eggs to terminate diapause, this Ease A4 activity increased characteristically with steep rise at the completion of the diapause development. But no increase of amino acid inc...

Zusammenfassung:The esterase A4 (Ease A4) has been obtained from Shi 108 Bombyx diapause eggs using isoelectric focusing. In the chilling of eggs to terminate diapause, this Ease A4 activity increased characteristically with steep rise at the completion of the diapause development. But no increase of amino acid incorporation into this Ease A4 was observed in the experiment of 14C-leucine injection into eggs and pupae. The low temperature causes a latent enzyme to be set in motion as a signal for the completion of the diapause development.
