Identification
Name: Ethylphosphonate
Description:Ethylphosphonate is a member of the chemical class known as Organic Phosphonic Acids and Derivatives. These are organic compounds containing phosphonic acid or a derivative thereof. phosphonoacetaldehyde is catalyzed by phosphonoacetaldehyde hydrolase. This is the first nucleic sequence report of the phosphonoacetaldehyde hydrolase, an enzyme involved in the carbon-phosphorus bond cleavage. (PMID 9332393). Phosphonates (Pn) are a large class of organophosphorus molecules that have direct carbon-phosphorus (C-P) bonds in place of the carbon-oxygen-phosphorus ester bond. In bacteria two pathways exist for Pn breakdown for use as a P source: the phosphonatase and C-P lyase pathways. These pathways differ both in regard to their substrate specificity and their cleavage mechanism. The phosphonatase pathway acts on the natural Pn alpha-aminoethylphosphonate (AEPn). In a two-step process it leads to cleavage of the C-P bond by a hydrolysis reaction requiring an adjacent carbonyl group. In contrast the C-P lyase pathway has a broad substrate specificity. It leads to cleavage of substituted Pn (such as AEPn) as well as unsubstituted Pn by a mechanism involving redox or radical chemistry. Due to its broad substrate specificity, the C-P lyase pathway is generally thought to be responsible for the breakdown of Pn herbicides (such as glyphosate) by bacteria.
