Investigations on the Mitochondria of the Housefly, Musca Domestica L
1. The ATPase activity of insect mitochondria has been investigated. A comparison was made to determine the distribution and nature of such activity in other isolated fractions of the house fly, Musca domestica L. 2. The ATPase in insect mitochondria is specific in that orthophosphate can be cleaved only from ATP. The Michaelis-Menten constant K(8) = 2.78 x 10(-3)M and V(max.) = 76 micrograms P...
متن کاملAnaerobic metabolism in the housefly, Musca domestica L.
Adult and immature individuals of many insect species can survive anaerobic conditions for periods ranging from 4 hr. to 4 days, and even in a few cases for longer periods up to 56 days (see Brand, 1946, for numerous references). The present paper describes an investigation into some effects of anoxia on adult Musca domestica. A preliminary account of part of this work has been published (Heslo...
متن کاملCircadian rhythm gene regulation in the housefly Musca domestica.
The circadian mechanism appears remarkably conserved between Drosophila and mammals, with basic underlying negative and positive feedback loops, cycling gene products, and temporally regulated nuclear transport involving a few key proteins. One of these negative regulators is PERIOD, which in Drosophila shows very similar temporal and spatial regulation to TIMELESS. Surprisingly, we observe tha...
متن کاملRegulation of Ovarian Ecdysteroid Production in the Housefly, Musca domestica
Highly purified Musca ecdysteroidogenin (ESG) was obtained by extracting housefly heads with an acid-ethanol-urea procedure followed by desalting on a Sephadex G25F column and fractionation on a Sephadex G50F column. Further fractionation was done on a semi-preparative C18 reverse-phase HPLC column with an acetonitrile gradient in 0.1% trifluoroacetic acid in water. Ecdysteroidogenic activity e...
متن کاملSegmentation gene expression in the housefly Musca domestica.
Drosophila and Musca both belong to the group of higher dipteran flies and show morphologically a very similar early development. However, these two species are evolutionary separated by at least 100 million years. This presents the opportunity for a comparative analysis of segmentation gene expression across a large evolutionary distance in a very similar embryonic background. We have analysed...
