Regulation of Macromolecular Synthesis by Low Molecular Weight Mediators contains the proceedings of the Workshop on Regulation of Macromolecular Synthesis by Low Molecular Weight Mediators held at Hamburg on May 29-31, 1979. The book discusses the functions and metabolism of guanosine 3',5'-bis(diphosphate); the purine nucleotides and sporulation; and the highly phosphorylated nucleotide in eukaryotes. The text also describes the alteration of translational mechanisms, as well as 2,5-oligoadenylic acid and interferon.
