Neutron diffraction analysis of Pseudomonas aeruginosa peptidyl-tRNA hydrolase 1

Acta Crystallogr F Struct Biol Commun. 2016 Mar;72(Pt 3):220-3. doi: 10.1107/S2053230X16001813. Epub 2016 Feb 19.

Abstract

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.

Keywords: Pseudomonas aeruginosa; antibiotic resistance; neutron diffraction; peptidyl-tRNA hydrolase 1; perdeuteration.
