COORDINATES FOR REMARK 5 CALCIUM IONS, CALCIUM-COORDINATING WATERS AND THE REMARK 5 ANTI-PSYCHOTIC DRUG TRIFLUOPERAZINE ARE GIVEN FOR BOTH THE REMARK 5 N-TERMINAL AND C-TERMINAL DOMAINS OF THE CALMODULIN REMARK 5 COMPUTER MODEL. THE MODEL WAS SUBJECTED TO 750 CYCLES OF REMARK 5 CONJUGATE GRADIENT ENERGY MINIMIZATION USING THE *GROMOS* REMARK 5 PACKAGE, PARAMETER SET 37D, WITH AN 8 ANGSTROMS CUTOFF. REMARK 6 REMARK 6 RESIDUE 115 IS NZ115 TRIMETHYLLYSINE. THE THREE METHYL REMARK 6 CARBONS FOR THIS RESIDUE ARE PRESENT AS HETATMS WITH REMARK 6 RESIDUE NAME TML.
