Iridescent virus type 6 infecting Galleria mellonella larvae contained an associated alkaline protease activity which appeared to be tightly bound to the virions and essentially localized on the outside of the viral particle. Under alkaline conditions the virus was degraded by proteolytic cleavage of viral envelope proteins. Proteolytic activity was not present in virus propagated in a permissive insect cell line or when purified from isolated larval fat-bodies instead from whole larvae. The results suggest that the protease associated with Iridescent virus type 6 is of larval origin.
感染大蜡螟幼虫的虹彩病毒6型含有一种相关的碱性蛋白酶活性，这种活性似乎与病毒粒子紧密结合，并且基本上定位于病毒粒子的外部。在碱性条件下，病毒通过病毒包膜蛋白的蛋白水解裂解而降解。在允许性昆虫细胞系中繁殖的病毒中，或者当从分离的幼虫脂肪体而非整个幼虫中纯化时，不存在蛋白水解活性。结果表明，与虹彩病毒6型相关的蛋白酶起源于幼虫。
