The Superimposition of the Active Sites of the SULT1E1-PAP-17β-estradiol Complex (1AQU) and the SULT1C2-PAP-PCP Complex (2GWH)

The SULT1E1-PAP-17β-estradiol complex is shown in yellow, and the SULT1C2-PAP-PCP complex is shown in grey. The PCP (chlorine atoms in green) and 17β-estradiol (EST) molecules are highlighted along with the catalytic His115 and PAP. See text for discussion.
