CRYSTALS WERE GROWN IN HANGING DROPS WHICH INITIALLY CONSISTED OF 0.11 MM PROTEIN IN 0.047 M HEPES BUFFER (PH 7.5) CONTAINING 1.82 MM GLUTATHIONE, 10.91

MM HNA-SG (GSH CONJUGATE OF 4-HYDROXYNONENAL), 9.1% ETHANOL, 4.5% ISOPROPANOL,

AND 6.5% PEG MONOMETHYL ETHER 5K (PH 7.5). THE DROPS WERE EQUILIBRATED AT 293 K AGAINST WELL SOLUTION CONTAINING 10% ISOPROPANOL AND 12% PEG MONOMETHYL ETHER 5K IN 80 MM HEPES BUFFER (PH 7.5).

ALL DATA WERE INCLUDED IN MAP CALCULATIONS.
