CRYSTAL STRUCTURE OF E. COLI AMINE OXIDASE COMPLEXED WITH TRANYLCYPROMINE
Overview
The X-ray crystal structure of the copper-containing quinoprotein amine oxidase from E. coli has been determined in complex with the antidepressant drug tranylcypromine to 2.4 A resolution. The drug is a racemic mix of two enantiomers, but only one is seen bound to the enzyme. The other enantiomer is not acting as a substrate for the enzyme as no catalytic activity was detected when the enzyme was initially exposed to the drug. The inhibition of human copper amine oxidases could be a source of side-effects in its use as an antidepressant to inhibit the flavin-containing monoamine oxidases in the brain.
About this Structure
1LVN is a Single protein structure of sequence from Escherichia coli with and as ligands. Active as Amine oxidase (copper-containing), with EC number 1.4.3.6 Full crystallographic information is available from OCA.
