REMARK 5 REMARK 5 RESIDUES 1 - 153 CORRESPOND TO THE THERMOSTABLE MUTANT REMARK 5 HUMAN CU,ZN SOD STRUCTURE WITH CYS 6 -> ALA AND CYS 111 -> REMARK 5 SER (REF. 1 AND PDB ENTRY 1SOS). THE HEPARIN-BINDING REMARK 5 PEPTIDE IS MODELLED AS A HELIX BASED UPON REF. 2 AND PDB REMARK 5 ENTRY 1PAI. THE FUSION PROTEIN STRUCTURE IS SUBSTANTIALLY REMARK 5 SIMILAR TO THAT OF HUMAN CU,ZN SOD ("HSOD"), WITH THE ADDED REMARK 5 GLY-PRO-GLY-A+ HELIX PEPTIDE FORMING AN EXTENSION THAT REMARK 5 PACKS AGAINST THE LOOPS AT ONE END OF THE BETA-BARREL. REMARK 5 SEQUERY, A PROGRAM THAT SEARCHES THE PROTEIN DATA BANK FOR REMARK 5 SEQUENCE PATTERNS (L. A. KUHN, M. E. PIQUE, M. A. SIANI, REMARK 5 E. D. GETZOFF, AND J. A.TAINER), WAS USED TO CONFIRM THAT REMARK 5 THE GLY-PRO-GLY LINKER HAS A CONFORMATION THAT ENCOURAGES REMARK 5 THE HELIX ATTACHED TO EACH HSOD SUBUNIT TO PACK IN THIS REMARK 5 ORIENTATION. THIS FORMS A TWO-HELIX HEPARIN-BINDING MOTIF REMARK 5 (REF. 2) IN THE DIMERIC PROTEIN. THE MODELLED STRUCTURE REMARK 5 GUIDED THE DESIGN OF A FUSION PROTEIN (HSOD-GLY-PRO-GLY-A+) REMARK 5 MADE BY RECOMBINANT DNA TECHNIQUES. THIS PROTEIN WAS REMARK 5 EXPRESSED IN ESCHERICHIA COLI AND SHOWN TO HAVE NORMAL SOD REMARK 5 ACTIVITY AND INCREASED RETENTION ON A HEPARIN AFFINITY REMARK 5 COLUMN RELATIVE TO WILD-TYPE HSOD. SEE JRNL ENTRY ABOVE REMARK 5 FOR DETAILS ON THE DESIGN, CONSTRUCTION, AND TESTING.
REMARK 6 REMARK 6 IN REGARD TO THE NON-TRANS PEPTIDES LISTED BELOW, IN ALL REMARK 6 CASES THE O-C-N-H BONDS ARE PLANAR BUT THE CA-C-N-CA BONDS REMARK 6 ARE NONPLANAR AND THERE IS A DISTORTION IN THE N-H BOND. REMARK 6 THIS MAY BE DUE TO ENERGY MINIZATION PROBLEMS, OR THE REMARK 6 PROCESS OF FORMING THE BOND BETWEEN RESIDUE 153 (THE REMARK 6 NATURAL C-TERMINUS OF HSOD) AND RESIDUE 154 (THE NATURAL REMARK 6 N-TERMINUS OF THE HEPARIN BINDING HELIX).
