Structural basis for catalytic and inhibitory divergence between archaeal and bacterial ammonia monooxygenases

Archaeal ammonia monooxygenase (AMO) is a cup-shaped homotrimer using a mononuclear CuD site; inhibitors bind bacterial AMO's dicopper center directly but apparently inactivate archaeal AMO indirectly by relocating copper.
