Pig kidney diamine oxidase was purified to homogeneity. The reaction product of the cofactor with p-nitrophenylhydrazine (pNPH) was liberated with pronase treatment and purified. 1H NMR, uv/vis, and electrospray tandem mass spectroscopy revealed it to be a dipeptide with the sequence topaquinone-pNP
An adduct with phenylhydrazine was formed with the purified pig kidney diamine oxidase and in parallel with the \(l\)-tyrosine decarboxylase from Streptococcus faecalis. The labeled enzymes were hydrolyzed by chemical hydrolysis and the adducts released by hydrolysis were isolated and identified fir
