NO ELECTRON DENSITY OBTAINED FOR THE MERCURIC ACETATE PART OF AMSULF IN THE ACTIVE SITE UNLIKE THE REPORTED CASE OF ISOZYME HCAII-AMSULF COMPLEX (A.E.ERIKSSON, DOCTORAL THESIS, UPSAALA, SWEDEN, 1988). 4: THE DRUG MOLECULE HAS WELL DEFINED ELECTRON DENSITY IN THE ACTIVE SITE OF THE ENZYME. WHEN THE DRUG BINDS TO THE ENZYME, HIS 200 IN THE LOOP REGION UNDERGOES A SIGNIFICANT CHANGE AS COMPARED TO THE NATIVE STRUCTURE. 5: ACTIVE SITE HYDROGEN BONDED SOLVENT NETWORK INVOLVING HIS 67 AND HIS 200 IS POSSIBLY IMPORTANT FOR THE CATALYTIC ACTIVITY AND INHIBITION OF THIS ISOENZYME. SEE ALSO FTNOTE 4. 6: ZINC ZN(II) IS THE CATALYTICALLY ESSENTIALL ZINC ION. 7: RESIDUES HG 266 AND HG 267 ARE THE TWO DISORDERED MERCURY SITES LOCATED NEAR RESIDUE CYS 212 WHICH ALSO SHOWS CONFORMATIONAL DISORDER IN THE (FO-FC) ELECTRON DENSITY MAP. 8: RESIDUES HG 264 AND HG 265 ARE TWO NEW MERCURY SITES NEAR RESIDUES 185-189. 9: ASSIGNMENT OF HG 269 NEAR LEU 147 IS TENTATIVELY BASED ON HEAVY ELECTRON DENSITY APPEARING IN THE (F0-FC) MAP. THE POSSIBILITY OF SOME OTHER IMPURITY GROUP CANNOT BE RULED OUT. |
