520			_aThis volume presents the latest science on the regulation of phosphate metabolism in E. coli, saccharomyces cerevisiae, and other important microbial systems. Based on a meeting held at Woods Hole, Massachusetts (September 1993) this book covers exciting new findings on the role of phosphate in signal transduction, protein structure, genetic control of pahtogenesis, and protein export and folding. Phosphate in Microorganisms will prove to be significant reading for anyone interested in bacterial metabolism and molecular biology of prokaryotic and lower eukaryotic organisms.
