Biosynthesis, Modification, and Processing of Cellular and Viral Polyproteins presents the proceedings of the international conference held in Hamburg-Blankenese on May 27-31, 1980. The book discusses topics on polyproteins, polyfunctional proteins, precursor proteins, as well as the differences in synthesis and processing of ACTH/endorphin peptides in primary cultures of anterior and intermediate lobes of the pituitary. The text also presents evidence for a self-cleaving precursor of virus-coded protease, RNA-replicase, and VPg; and the role of Pr180gag-pol in the characterization and genetic analysis of retrovirus maturation.
