ALTERNATE POSITIONS ARE PRESENT FOR SIDE CHAIN OF RESIDUES ...Details: N-TERMINUS FROM RESIDUE 1 TO 8, IN SUBUNIT A AND 1 TO 10 IN SUBUNIT B, ARE NOT VISIBLE IN THE ELECTRON DENSITY, DUE TO FLEXIBILITY. ALTERNATE POSITIONS ARE PRESENT FOR SIDE CHAIN OF RESIDUES 19A, 79A, 81A, 123A, 76B THE ATOMS CONCERNED HAVE OCCUPANCY BETWEEN 0.0 AND 1.0 AND A SEGID AC1 AND AC2 OFTEN, OCCUPANCY VALUES LOWER THAN 1.0 APPEARED TO JUSTIFY BETTER THE ELECTRON DENSITY. FOR THIS REASON WE HAVE KEPT THIS LOW OCCUPANCY FOR SEVERAL SIDE CHAIN ATOMS.
