Interactions of two distinct quinoprotein amine oxidases from Aspergillus niger, AO-I and AO-II, with active-site covalent modifiers have been investigated. Both enzymes are inhibited similarly by phenylhydrazine or p-nitrophenylhydrazine, forming an orange Schiff base with a carbonyl group of topaquinone

Analytical biochemistry, 230(1), 159-166 (1995-09-01)
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

The total plasmalogen content of lingual and other tissues was analyzed using the iodine-addition (Method 1), the p-nitrophenylhydrazone (Method 2), and the two-dimensional thin layer chromatography procedure (Method 3). Methods 1 and 2 were simple, rapid and reproducible, yielding values

Journal of inorganic biochemistry, 56(2), 127-141 (1994-11-01)
An improved purification scheme for an amine oxidase from equine plasma (EPAO), a nonruminant source, is described and the protein's active-site is characterized. EPAO is dimeric and contains one Type-2 Cu(II) ion per monomer. The EPAO Cu(II) site is spectroscopically

Compositional analyses of heparin (Hep) and heparan sulfate (HS) have been undertaken with disaccharide units obtained by either enzymatic digestion with heparitinases or hydrazinolysis/deamination reaction of polysaccharides. Unsaturated disaccharide units generated by the enzymatic method are detectable on HPLC with
