abstract = {Heterotrimeric glutamine amidotransferase CAB (GatCAB)
possesses anammonia-self-sufficient mechanism in which
ammonia is produced and usedin the inner complex by GatA and
GatB, respectively. The X-ray structure ofGatCAB revealed
that the two identified active sites of GatA and GatB
aremarkedly distant, but are connected in the complex by a
channel of 30 A ˚ inlength. In order to clarify whether
ammonia is transferred through this channelin GatCAB by
visualizing ammonia, neutron diffraction studies are
indispensable.Here, GatCAB crystals were grown to
approximate dimensions of2.8 0.8 0.8 mm (a volume of 1.8
mm3) with the aid of a polymer usingmicroseeding and
macroseeding processes. Monochromatic neutron
diffractiondata were collected using the neutron
single-crystal diffractometer BIODIFF atthe Heinz
Maier-Leibnitz Zentrum, Germany. The GatCAB crystals
belonged tospace group P212121, with unit-cell parameters a
= 74.6, b = 94.5, c = 182.5 A ˚ andwith one GatCAB complex
(molecular mass 119 kDa) in the asymmetric unit.This study
represented a challenge in current neutron diffraction
technology.},
