tetranitromethane ( tnm ) was employed as an electrophilic reagent to probe for the lysyl oxidase-catalyzed processing of n-butylamine to an intermediate carbanion during the oxidation of this amine to n-butyraldehyde according to a prior description of the use of tnm to trap enzyme-generated carbanion intermediates ( christen , p. and riordan , j. f. ( 1968 ) biochemistry 7 , 1531-1538 ) .
