Complexes of the copper-containing amine oxidase from Arthrobacter globiformis with the inhibitors benzylhydrazine and tranylcypromine

摘要

Complexes of Arthrobacter globiformis amine oxidase (AGAO) with the inhibitors benzylhydrazine and tranylcypromine (an antidepressant drug) have been refined at 1.86 and 1.65 Å resolution, respectively. Both inhibitors form covalent adducts with the TPQ cofactor. A tyrosine residue, proposed to act as a gate to the AGAO active site, is in its open conformation.
