Perdeuterated peptidyl-tRNA hydrolase 1 from Pseudomonas aeruginosa was crystallized for structural analysis using neutron diffraction. Crystals of perdeuterated protein were grown to 0.15 mm(3) in size using batch crystallization in 22.5% polyethylene glycol 4000, 100 mM Tris pH 7.5, 10%(v/v) isopropyl alcohol with a 20-molar excess of trilysine as an additive. Neutron diffraction data were collected from a crystal at room temperature using the MaNDi single-crystal diffractometer at Oak Ridge National Laboratory.
