The S3'/S4' subsites of E. coli SPase. Rearrangements of side chain residues at S3'/S4' subsites in the crystallographic structure of E. coli type 1 SPase (PDB ID: 1B12). A, The side chain of Asp276 is exposed to interact with amino acid residues at positions -3 and -4. B, Rearrangements of Asp276 and Arg282 result in a positively charged pocket at S3'/S4' subsites.
