Nitric oxide covalently labels a 6-hydroxydopa-derived free radical intermediate in the catalytic cycle of copper/quinone-containing amine oxidase from lentil seedlings
{{output}}
The reaction of NO-derivatized polyamines called "NONOates" with an amine oxidase from lentil seedlings was studied. 3,3-Bis(aminoethyl)-1-hydroxy-2-oxo-1-triazene (DETA-NONOate) and 3,3'-(hydroxynitrosohydrazino)bis-1-propanamine (DPTA-NONOate) were found to ... ...
