Purification and Characterization of a Juvenile Hormong Binding Protein from Whole Body Homogenates of the Wax Moth, Galleris mellonella Final Instar Larvae
꿀벌부채명나방 종령유충에서 유약호르몬 결합단백질의 정제와 특성
Abstract
A juvenile hormone binding protein (JHBP) has been isolated from the whole body homogenate of Galleria rnellonella final instar larvae by gel filtration. The isolated protein is homogenous as judged by column chromatography and gel electrophoresis in the presence and absence of denaturing agent. The JHBP has a relative molecular weight of 32 k by denaturing gel electrophresis and 28 k by gel filtration. The protein exhibits a dissociation constant of 3.9 x M for JH 111.
꿀벌부채명나방 종령유충의 whole body에서 gel filtration 방법으로 유약호르몬 결합 단백질을 분리, 정제하였다. 분리된 단백질은 column chromatography법과 전기영동법에 의해 등가성을 확인하였다. 이 결합단백질은 전기 영동법에 의해 32K, gel filtration 에 의해 28K의 상대적 분자량을 나타냈다. 또한, JH III에 대한 해리도는 3.9
