Accumulation of intermediates of the carbon-phosphorus lyase pathway for phosphonate degradation in phn mutants of Escherichia coli

Abstract

The catabolism of phosphonic acids occurs in Escherichia coli by the carbon-phosphorus lyase pathway, which is governed by the 14-cistron phn operon. Here, several compounds are shown to accumulate in strains of E. coli with genetic blocks in various phn cistrons when the strains are fed with phosphonate.
