Microbial Metabolism of Reduced Phosphorus Compounds

Abstract

The field of bacterial phosphorus (P) metabolism has undergone a significant transformation in the past decade owing to the elucidation of widespread and diverse pathways for the metabolism of reduced P compounds. The characterization of these pathways dramatically changes the current and narrow view of P metabolism and our understanding of the forms in which P is produced and available in the environment. In this review, recent investigations into the biochemical pathways and molecular genetics of reduced P metabolism in bacteria are discussed. Particular attention is paid to recently elucidated metabolic reactions and the genetic characterization of biosynthesis of organic reduced P compounds and to the pathways for oxidation of the inorganic reduced P compounds hypophosphite and phosphite.
