: / Heme oxygenase-like / Heme Oxygenase; Chain A / Haem oxygenase-like, multi-helical / Up-down Bundle / Mainly Alpha / cytosol / ACETATE ION / TenA family transcriptional activator-like protein
BIOMOLECULE: 1 THIS ENTRY CONTAINS THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT WHICH CONSISTS OF 2 CHAIN(S) ...BIOMOLECULE: 1 THIS ENTRY CONTAINS THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT WHICH CONSISTS OF 2 CHAIN(S). SEE REMARK 350 FOR INFORMATION ON GENERATING THE BIOLOGICAL MOLECULE(S). SIZE EXCLUSION CHROMATOGRAPHY WITH STATIC LIGHT SCATTERING SUPPORTS THE ASSIGNMENT OF A HEXAMER AS A BIOLOGICALLY SIGNIFICANT OLIGIMERIZATION STATE.

HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS 2. A MET-INHIBITION PROTOCOL WAS USED FOR SELENOMETHIONINE INCORPORATION DURING PROTEIN EXPRESSION. THE OCCUPANCY OF THE SE ATOMS IN THE MSE RESIDUES WAS REDUCED TO 0.7 TO ACCOUNT FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION. 3. POOR DENSITIES: THE DENSITY FOR 239 AND 240 ARE POOR. THE DENSITY IS AMBIGUOUS AT ARG 10 IN BOTH A AND B CHAINS, AS A RESULT, THE MODEL BUILT FOR THIS RESIDUE IS LESS RELIABLE. 4. A CHAIN OF DENSITY NEAR DIMER-DIMER INTERFACE (NEAR B178) IS TENATIVELY MODELLED AS A WATER CHAIN (151,167,171,205,223).
