ISOLATION AND SOME PROPERTIES OF AN ALKALINE PROTEASE IN NUCLEAR POLYHEDROSIS VIRUS OF ATTACUS RICINI

  • Available online: 05 September 1987
  • The paper confirmed the presence of alkaline protease in the nuclear polyhedra of the Attacus ricini and the characteristics of the protease. When the nuclear polyhedra was exposed to alkaline solution, a proteolytic enzyme in the polyhedra degraded the major structural proteins of polyhedra into proteins with the lower molecular weight, The proteolytic activity showed an optimum temperature of 40℃ and an optimum pH of 11 to 12. The activity was inhibited by metallic ions such as Hg~(2+) and Cu~(2+). The en...
