REMARK 220 REMARK 220 EXPERIMENTAL DETAILS REMARK 220 EXPERIMENT TYPE : THEORETICAL MODELLING REMARK 220 REMARK 220 REMARK: THE STRUCTURE PRESENTED IN THIS ENTRY IS A MODEL OF REMARK 220 HUMAN PARAOXONASE 1 (PON1) BASED ON HOMOLOGY TO 1E1A REMARK 220 (DFPASE FROM LOLLIGO VULGARIS). THE STRUCTURE WAS REMARK 220 DERIVED FROM AN INITIAL HOMOLOGY MODEL TO DFPASE AFTER REMARK 220 ADDITION OF RESIDUES 40-51, CREATION OF THE SINGLE REMARK 220 DISULFIDE BOND, AND AN UNCONSTRAINED DYNAMICS SIMULATION REMARK 220 IN A PRESSURIZED WATER BOX FOR 30 PS (30,000 TIMESTEPS) REMARK 220 FOLLOWED BY CONSTRAINED MINIMIZATION FOR 10 TIMESTEPS TO REMARK 220 RESTORE PLANARITY TO AROMATIC RINGS. THE HOMOLOGY MODEL REMARK 220 WAS BUILT USING INSIGHT/DISCOVER'S HOMOLOGY MODULE. THE REMARK 220 DYNAMICS RUN WAS PERFORMED, AFTER MANY LOCAL REMARK 220 MINIMIZATIONS, USING INSIGHT/DISCOVER'S DISCOVER3 MODULE REMARK 220 ON SILICON GRAPHICS HARDWARE PROVIDED BY THE INSTITUTE REMARK 220 OF CHEMICAL DEFENSE, APG, MD, USA AS WELL AS HARDWARE REMARK 220 PROVIDED BY THE NATIONAL CANCER INSTITUTE'S ADVANCED REMARK 220 BIOMEDICAL COMPUTING CENTER, FREDERICK, MD, USA. THE REMARK 220 DISCOVER DYNAMICS WAS RUN UNDER NPT WITH 1 FS TIMESTEP, REMARK 220 .1 MPA UNIFORM PRESSURE IN A WATER BOX WITH 76 ANG REMARK 220 SIDES. ALL CALCULATIONS WERE PERFORMED USING THE CVFF REMARK 220 FORCEFIELD.
REMARK 225 REMARK 225 THEORETICAL MODEL REMARK 225 THE COORDINATES IN THIS ENTRY REPRESENT A MODEL STRUCTURE. REMARK 225 PROTEIN DATA BANK CONVENTIONS REQUIRE THAT CRYST1 AND REMARK 225 SCALE RECORDS BE INCLUDED, BUT THE VALUES ON THESE REMARK 225 RECORDS ARE MEANINGLESS.
