Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 6J4O
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 EVAPORATION 8.2 293 For crystallization of V2c-SVBP C58S in complex with the maTail peptide the components were mixed in a 1:3 molar ratio and incubated at room temperature for 24 h before setting up crystallization trials. The resulting V2c-SVBP S58C-maTail complex was crystallized in 1.4 M sodium/potassium phosphate, pH 8.2.
