OMITTING REMARK 3 RESIDUE NUMBERS 75-83 REFLECTS THE ENGINEERED DELETION AND REMARK 3 PRESERVES WILD TYPE NUMBERING OF RESIDUES 84-275. THE REMARK 3 ACTIVE SITE IS THE CATALYTIC TRIAD ASP 32, HIS 64, CYS 221 REMARK 3 DESCRIBED IN THE SITE RECORD BELOW. SECONDARY STRUCTURE REMARK 3 STRUCTURE ASSIGNMENT IS ACCORDING TO KABSCH AND SANDER REMARK 3 (BIOPOLYMERS 22, 2577-2637, 1983). RESIDUE SER 221 IS REMARK 3 COVALENTLY LINKED TO THE INHIBITOR DIISOPROPYL REMARK 3 FLUOROPHOSPHATE (HET GROUP DFP). ONLY ONE OF THE TWO REMARK 3 ISOPROPYL GROUPS IS VISIBLE AND INCLUDED IN THE MODEL. SEE REMARK 3 HETATM RECORDS DFP, RESIDUE NUMBER 288. CONECT RECORDS REMARK 3 SPECIFY BONDING.
