REMARK 5 REMARK 5 THESE COORDINATES WERE GENERATED BY HOMOLOGY MODELING REMARK 5 ONTO THE X-RAY CRYSTAL STRUCTURES OF CHYMOTRYPSIN, REMARK 5 KALLIKREIN, TONIN AND TRYPSIN. THE KALLIKREIN LOOP OF REMARK 5 PSA (AT RESIDUE 95) WAS SUBMITTED TO A 50-PS REMARK 5 HIGH-TEMPERATURE MOLECULAR DYNAMICS SIMULATION. REMARK 5 CALCULATION OF THE SOLVATION ENERGY WAS CARRIED OUT FOR REMARK 5 EACH STRUCTURE. THE MODEL REPORTED IN THIS FILE REMARK 5 CORRESPONDS TO THE LOOP STRUCTURE HAVING THE LOWEST REMARK 5 SOLVATION ENERGY. THIS STRUCTURE WAS JUDGED APPROPRIATE REMARK 5 FOR THE STRUCTURAL ANALYSIS OF THE MODEL.
REMARK 6 REMARK 6 THE CHYMOTRYPSINOGEN NUMBERING IS MAINTAINED THROUGHOUT REMARK 6 THIS FILE.
REMARK 7 REMARK 7 CAT IS THE SERINE PROTEASE CATALYTIC TRIAD (SEE SITE REMARK 7 RECORDS BELOW).
REMARK 8 REMARK 8 PSA HAS 15 RESIDUES AT THE N-TERMINUS. THE FIRST 8 ARE REMARK 8 CLEAVED. THE ENZYME IS CALLED PREPROENZYME. NO X-RAY REMARK 8 STRUCTURES OF PREPROENZYME ARE KNOWN. THE FOLLOWING 7 REMARK 8 RESIDUES ARE ALSO CLEAVED, AND IT SEEMS THAT NO GROUPS HAVE REMARK 8 BEEN ABLE TO IDENTIFY A CIRCULATING PSA PROTEIN WITH THESE REMARK 8 7 RESIDUES.
