1.1.5.9 D-glucose + a quinone - 1.1.5.9 additional information enzyme participates in strengthening the encapsulation and in killing reaction, via reaction with quinones generated by phenolidase and subsequent production of free radicals 1.1.5.9 additional information enzyme participates in the immune reaction by donating electrons during regeneration of its cofactor FAD. The enzyme is required for the generation of reactive oxygen species by hemocytes at the encapsulation site. The enzyme activity increases immediately at post-oviposition and post-injection of purified polyDNA viruses
