THE APO-E4 REMARK 400 ISOFORM DIFFERS FROM THE WILD-TYPE (E3) PROTEIN BY THE REMARK 400 MUTATION CYS 112-->ARG. THE MUTANT PROTEIN SHOWS NORMAL REMARK 400 LDL RECEPTOR BINDING BUT ALTERED LIPOPROTEIN BINDING. REMARK 400 WHEREAS WILD-TYPE APO-E BINDS BOTH HIGH DENSITY LIPOPROTEIN REMARK 400 (HDL) AND VERY LOW DENSITY LIPOPROTEINS (VLDL), THE APO-E4 REMARK 400 MUTANT STRONGLY PREFERS VLDL OVER HDL. THE STRUCTURE OF TH REMARK 400 E4 MUTANT WAS DETERMINED USING STARTING PHASES OBTAINED FRO REMARK 400 THE E3 PROTEIN. REMARK 400 REMARK 400 SECONDARY STRUCTURE WAS ASSIGNED USING THE *DEFINE* PROGRAM REMARK 400 (RICHARDS AND KUNDROT, PROTEINS V. 3, 71 (1988)).
