Abstract: | We have found that the phenol oxidase activity in 50-hr Drosophila melanogaster pupae is much greater than that of adult flies. The mutants lz and lz
g have all of the phenol oxidase components present in wild type, whereas the mutant tyr-1 has all of the wild-type components but the activity of each component is greatly reduced in comparison with wild-type activity. The newly discovered lozenge allele, lz
rfg, lacks all phenol oxidase activity.Predoctoral fellow supported by Grant GM 1974 from the National Institute of General Medical Sciences, National Institutes of Health.The Oak Ridge National Laboratory is operated for the U.S. Atomic Energy Commission by Union Carbide Corporation. |
