Pseudomonas putida utilized methyl parathion as sole carbon and (or) phosphorus source. The bacterium elaborated the enzyme organophosphorus acid anhydrase, which hydrolyzed methyl parathion to p-nitrophenol. p-Nitrophenol was further degraded to hydroquinone and 1,2,4-benzenetriol. The final ring compound, 1,2,4-benzenetriol, was cleaved by benzenetriol oxygenase to maleyl acetate.

D008743	Methyl Parathion	The methyl homolog of parathion. An effective, but highly toxic, organothiophosphate insecticide and cholinesterase inhibitor.	Metaphos,Parathion Methyl,Dalf,Metacid 50,Methylparathion,Vofatox,Wofatox
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
