NON-CRYSTALLOGRAPHIC SYMMETRY THE TRANSFORMATIONS PRESENTED ON THE MTRIX RECORDS BELOW DESCRIBE NON-CRYSTALLOGRAPHIC RELATIONSHIPS AMONG ATOMS IN THIS ENTRY. APPLYING THE APPROPRIATE MTRIX TRANSFORMATION TO THE RESIDUES LISTED FIRST WILL YIELD APPROXIMATE COORDINATES FOR THE RESIDUES LISTED SECOND. CHAIN IDENTIFIERS GIVEN AS "?" REFER TO CHAINS FOR WHICH ATOMS ARE NOT FOUND IN THIS ENTRY.
