REMARK 400 REMARK 400 COMPOUND REMARK 400 REMARK 400 MALE-B363 IS AN INSERTION/DELETION MUTANT OF THE E. COLI REMARK 400 MALTODEXTRIN-BINDING PROTEIN (MBP) CARRYING THE AMINO-ACID REMARK 400 SEQUENCE OF A B-CELL EPITOPE FROM THE PRES2 REGION OF THE REMARK 400 HEPATITIS B VIRUS SURFACE ANTIGEN. AMINO ACIDS BELONGING REMARK 400 TO THE PRES2 EPITOPE ARE DESIGNATED 132E TO 145E REMARK 400 (POSITIONS 132-145 OF THE VIRAL SURFACE ANTIGEN). RESIDUES REMARK 400 DESIGNATED 364I, 365I, AND 380I-389I, WHICH FLANK THE REMARK 400 EPITOPE SEGMENT, RESULT FROM THE GENETIC CONSTRUCTION USED REMARK 400 TO PERMIT THE INSERTION. NUMBERING OF THE INSERTED REMARK 400 SEQUENCE IS THUS 364I, 365I, 132E TO 145E, AND 380I TO REMARK 400 389I. THESE RESIDUES REPLACE WILD-TYPE MBP RESIDUES FROM REMARK 400 POSITIONS 364 - 370. THE NUMBERING OF MBP RESIDUES IN THIS REMARK 400 ENTRY CORRESPONDS TO THE SEQUENCE POSITIONS OF WILD-TYPE REMARK 400 MBP.
