3.4.23.32	enzyme-(acetyl-FKF-(3S,4S)-phenylstatinyl)-LR-NH2 complex and enzyme-acetyl-FKF(2R,3S)-phenylisoseryl-ALR-NH2 complex. Native crystals of the enzyme are grown at room temperature by the hanging-drop vapor diffusion method from 42% saturated ammonium sulfate, 10% ethylene glycol and 0.1 M sodium acetate buffer (pH 4.0). These crystals are then soaked in solutions of varying concentrations of the transition state analogs (acetyl-FKF-(3S,4S)-phenylstatinyl)-LR-NH2 and acetyl-FKF(2R,3S)-phenylisoseryl-ALR-NH2	
3.4.23.32	purified enzyme complexed with angiotensin II, hanging drop method, room temperature, from 42% saturated ammonium sulfate, 0.1 M sodium acetate, pH 4.0, 10% v/v ethylene glycol, crystals are soaked in cryosolution containing 30% glvcerol, 45% saturated ammonium sulfate,and 0.1 M sodium acetate, pH 4.0, heavy atom derivatizing, X-ray diffraction structure determination and analysis at 1.9-2.5 A resolution, molecular modeling and multiple isomorphous replacement phasing	
3.4.23.32	the three-dimensional structure of SGP is determined by X-ray crystallography. The polypeptide folds into a beta-sandwich that has seven antiparallel beta-strands in each of the two sheets
