Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 1H7S
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 5 289.15 Crystals were obtained in conditions containing 4% tacsimate pH 5 (v/v) and 25% PEG 3350 (w/v). The concentrated PMS2 G207E protein (7 mg/mL) was combined with 0.1ul of an additive (0.1 M calcium chloride dehydrate) prior to the addition of crystallization reagent in a 1:1 ratio.
