The effector lipid consisted of dATP coupled through the 7-phosphoryl group and an€-aminocaproyl linker to phosphatidylethanolamine. Two-dimensional crystals of B1 reductase, like those of antibodies and cholera toxin obtained previously, formed under physiologic conditions of pH and ionic strength, with no precipitant added to the solution. There was, however, a requirement for dTTP in the solution, presumably to ensure binding of the dATP-lipid at only one of two effector sites on the enzyme. Diffraction from the crystals extended to 18-A resolution in negative stain, with unit cell parameters a= 110 A, b= 277 A, and 7=
