Crystal structure of human insulin mutant B20 D-ala, B23 D-ala
Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 1B2A
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 8 294 These insulin crystals were obtained from a co-crystallization experiment with insulin receptor fragment IR310.T. Crystals were formed in the presence of IR310.T as detailed for the IR310.T complex with native human insulin - in Menting et al. 2013, Nature 493:241-245. Crystallant was 0.7 M trisodium citrate, 0.1 M imidazole-HCl pH 8.0, VAPOR DIFFUSION, HANGING DROP, temperature 294K
