2QFE Distal C2-Like Domain of Human Calpain-7 Deposited 2007-06-27 Assembly 1 Protein monomer Monomer；Protein × 1 PDB declaration: monomeric（1） Consistent with protein count
Chain A 684–813（130 aa） Fragment：Distal C2-Like Domain
Not recorded BR BROMIDE ION × 18 X-RAY DIFFRACTION
X-ray crystallization conditions VAPOR DIFFUSION, HANGING DROP；pH 7；298 K；The crystals were grown in 1.4 M NaKPO4 pH 7.0, by mixing equal volumes of the precipitant solution and 13 mg/mL protein in binding buffer (500 mM NaCl, 50 mM Tris pH 8.0). The crystal was soaked for 1 hour in a solution containing 2 M NaBr., VAPOR DIFFUSION, HANGING DROP, temperature 298.0K
Resolution 1.45 Å R-free 0.215
8UC6 Calpain-7:IST1 Complex Deposited 2023-09-25 Assembly 1 Protein heterocomplex Heteromer；Protein × 2 PDB declaration: dimeric（2） Consistent with protein count
Chain C 1–165（165 aa）
Not recorded No recorded non-water small molecule X-RAY DIFFRACTION
X-ray crystallization conditions VAPOR DIFFUSION, SITTING DROP；pH 4.2；294 K；Both proteins were purified and concentrated to 20 mg/ml in buffer containing 25 mM Tris, pH 7.2, 150 mM NaCl, 1 mM TCEP, 0.5 mM EDTA. The proteins were mixed in a 1:2 molar ratio (CAPN7:IST1). Crystals grew at 21 C (294 K) in Rigaku Wizard Cryo condition D5 (25% (v/v) 1,2-Porpanediol, 100 mM Sodium phosphate dibasic/Citric acid pH 4.2, 5% (w/v) PEG 3000, 10% (v/v) Glycerol. Crystals were transferred briefly to crystallization buffer supplemented with 25% added glycerol prior to plunging in liquid nitrogen
Resolution 2.70 Å R-free 0.285

This page presents structural evidence recorded in PDB/mmCIF.“No recorded non-water small molecule” does not prove that the experimental sample was ligand-free; experimental conditions belong to the PDB experiment, while ligands and copy counts are shown for each biological assembly.
