Difference tags compare only the current result set; every original PDB and assembly record remains separate.

Related-Structure Differences

Each row represents one biological assembly in one PDB entry; multiple monomers of the same protein are listed separately.

PDB Entry Assembly / Oligomeric State Construct Mutations and Modifications Ligands, Ions and Non-polymers Experimental Method Experimental Conditions Structure Quality
1CII COLICIN IA Deposited 1997-01-08 Assembly 1 Protein monomer Monomer；Protein × 1 PDB declaration: monomeric（1） Consistent with protein count
Chain A 23–624（602 aa）
Not recorded No recorded non-water small molecule X-RAY DIFFRACTION
X-ray crystallization conditions vapor diffusion - hanging drop - streak seeding；pH 5.2；PROTEIN WAS CRYSTALLIZED BY HANGING-DROP VAPOR DIFFUSION AGAINST RESERVOIRS OF 1.0 M NH4(SO4)2, 20 MM NA-CITRATE (PH 5.2), 200 MM NACL, STARTING WITH 6 MICROLITERS OF PROTEIN AT 2 MG/ML IN 20 MM NA-CITRATE (PH 5.2), 200 MM NACL, 5 MM DTT, AND 4 MICROLITERS RESERVOIR SOLUTION. THESE DROPS OF MUTANT PROTEIN WERE STREAK-SEEDED FROM STOCKS GENERATED FROM CRUSHED DIFFRACTION-QUALITY WILD-TYPE COLICIN IA CRYSTALS. CRYSTALS WERE HARVESTED TO 1.1 M NA2SO4, 200 MM NACL, 20 MM NA-CITRATE (PH 5.2), AND 5 MM DTT. FOR DERIVATIZATION, CRYSTALS WERE WASHED IN DTT-FREE HARVEST BUFFER AND SOAKED FOR ONE WEEK IN 1 MM CH3HGCL., vapor diffusion - hanging drop - streak seeding

Chain B 282–385（104 aa） Fragment：R domain of Colicin Ia
Not recorded LDA LAURYL DIMETHYLAMINE-N-OXIDE × 2 X-RAY DIFFRACTION
X-ray crystallization conditions VAPOR DIFFUSION, HANGING DROP；pH 6.2；294 K；9 G/L PROTEIN IN 0.02M TRIS PH7.5, 0.2M NACL, 0.05% LDAO, 0.45% C8E4, 3% HEPTANETRIOL MIXED AT 1:1 RATIO WITH 0.1M MES PH6.2, 10% GLYCEROL, 22% PEG 2000 MME, VAPOR DIFFUSION, HANGING DROP, temperature 294K
Resolution 2.50 Å R-free 0.249

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.
