REMARK 3 THERE ARE TWO DIFFERENT CONFORMATIONS FOR EACH ATOM. REMARK 3 FOR CONVENIENCE, THE AUTHOR ASSIGNED AS A DOUBLE REMARK 3 CONFORMATION ONLY ONE OF THE ATOMS.(CD2 OF LEU 90, REMARK 3 OE1 OF GLU 218 AND CG1 OF VAL 325) REMARK 3 THUS THE OCCUPANCIES OF THE ALTERNATE CONFORMATIONS REMARK 3 ARE GREATER THAN 1.00 AND THERE ARE CHIRALITY ERRORS REMARK 3 AT THESE ATOMS. REMARK 3 THE CHIRALITY ERRORS APPEAR AT CB (ILE A 105) AND CG (BLEU A 365). REMARK 3 ABOUT LEU 365, THE AUTHOR COULD SEE TWO CONFORMATIONS, BUT ONLY REMARK 3 THE ATOM CG REMARK 3 WAS OBVIOUS. REMARK 3 THE OTHER ATOMS (RESPECTIVELY CD1 AND CD2), IF IN AN OTHER REMARK 3 CONFORMATION, REMARK 3 WOULD HAVE BEEN REMARK 3 TOO CLOSE THAN THE FIRST CONFORMATION. REMARK 3 THE AUTHOR ONLY APPLIED TWO CONFORMATIONS FOR THE CG ATOM. REMARK 3 ABOUT ILE 105, THE AUTHOR COULD SEE DENSITY FOR AN OTHER REMARK 3 CONFORMATION ONLY FOR A CG ATOM, BUT NOTHING FOR THE CD1. REMARK 3 THE AUTHOR ASSIGNED ONLY 2 CONFORMATIONS FOR THE CG2 ATOM. REMARK 3 THESE ARE THE REASONS FOR THE CHIRALITY ERRORS.
