Variations in the surrounding amino acid residues in the SGSH protein by the substitution with a deleterious amino acid. (a) Native arginine (green) at position 74 with its surrounding amino acid residues and cysteine (red) with its surrounding amino acid residues. (b) Native serine (green) at position 66 with its surrounding amino acid residues and tryptophan (red) with its surrounding amino acid residues. (c) Native arginine (green) at position 245 with its surrounding amino acid residues and histidine (red) with its surrounding amino acid residues
