IN SPITE OF AN EIGHT-RESIDUE REDUNANCY BETWEEN RNASE 1 - 118 AND RNASE 111 - 124, NO REDUNDANT STRUCTURE IS SEEN IN THE CRYSTAL. RESIDUES 114 - 118 OF RNASE 1 - 118 AND RESIDUES 111 - 113 OF RNASE 111 - 124 DO NOT APPEAR IN THE MAP. 2. HIS 119 IS PREDOMINANTLY IN THE CONFORMATION REPORTED AS A MINOR OCCUPANCY BY BORKAKOTI ET AL. (ACTA CRYSTALLOGR.,SECT. B, V. 38, P. 2210, 1982, PDB ENTRY 1RN3).
