摘要: Developmental profiles for a number of molting fluid (MF) enzyme activities were established and related to the progress pupal cuticle degradation during four days that precede eclosion adult tobacco hornworms. Cuticle degrading activity, protease 1 (MFP-1), 2 (MFP-2) all increased in activity at time loss material from old occurred. In contrast, chitinase β-acetylglucosaminidase did not parallel weight cuticle. These results are consistent with hypothesis proteolytic is prerequisite action on chitin. © 1993 Wiley-Liss, Inc.
