[RNP-complex stoichiometry of Bombyx mori nuclear polyhedrosis virus polyhedra]
Abstract:
By gel-filtration through Sephacryl S-300 it was shown that RNP A complex present in polyhedra of Bombyx mori nuclear polyhedrosis virus has molecular weight (M(w)) about 700 kDa. It was shown that RNP A with M(w) 788 kDa is composed of two polyhedrin 13S-associates with M(w) 342 kDa, two p14 polypeptide with M(w) 14 kDa, two 21 kDa small non-coded RNAs and two 17 kDa small non-coded RNAs. The model of RNP A formation from components making it is proposed. The complex role in the course of polyhedron formation and its role in the course of infection are discussed.

Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
