The crystal structure of a Fab fragment (Fab3-2C2) of a monoclonal antibody raised against aromatase cytochrome P450 P450arom) has been determined at 3.0 A resolution. P450arom is a membrane bound enzyme responsible for the catalysis of indrogens to estrogens, the process of aromatization, and hence has been implicated in hormone-dependent breast cancer.(More)
The preparation and characterization of the Fab and F(ab')2 fragments of a murine monoclonal antibody specific for aromatase cytochrome P-450 and which is suppressive of estrogen biosynthesis are described. This monoclonal antibody, MAb3-2C2, was purified from murine ascites using protein A affinity chromatography and digested with immobilized papain to(More)
