SHEET A SHORT TWO-STRANDED ANTI-PARALLEL BETA-SHEET IS FORMED BY RESIDUES 54 - 63, ENCLOSING A TYPE II' TURN BETWEEN RESIDUES 57 AND 60. THERE ARE TWO INTERSTRAND HYDROGEN BONDS BETWEEN RESIDUES 57 AND 60.
NO RESTRAINTS WERE PLACED ON CADMIUM IONS DURING REFINEMENT. CONSEQUENTLY THERE ARE CLOSE CONTACTS BETWEEN SOLVENT MOLECULES AND SIDE-CHAIN ATOMS INVOLVED IN CADMIUM LIGATION.
