Content:
Current Topics in Cellular Regulation, Volume 18: Biological Cycles covers topics on the events of molecular biology, cellular communication, and the merging of cell structure to biochemical function. The book discusses the ornithin-urea cycle; the cycles of glutathione metabolism and transport; and the role of multienzymatic proteins in mammalian pyrimidine biosynthesis. The text also describes the significance of interconvertible enzyme cycles in cellular regulation; regulation of mammalian pyruvate dehydrogenase complex by a phosphorylation-dephosphorylation cycle; replenishment of citric
