A, results showing ASA fitted into 1.5 σ ( Fo − Fc ) electron density. A few residues in the proximity are also indicated. The W-1 corresponds to W-618 in 3GCL. B, SHA fitted into 1.5 σ ( Fo − Fc ) electron density. C, SHA fitted into 1.5 σ ( Fo − Fc ) electron density. The heme moiety, distal Gln-105, and His-109 are also shown. Figures were drawn using Pymol (55).
