THE MYB REMARK 5 DNA-BINDING DOMAIN CONSISTS OF 3 IMPERFECT REPEATS OF ~50 REMARK 5 AMINO ACIDS. SINGLE REPEATS APPEAR TO BE DISTANTLY RELATED REMARK 5 TO THE HOMEODOMAIN SEQUENCES, WHICH ARE PART OF THE REMARK 5 HELIX-TURN-HELIX FAMILY. TO ALIGN THE MYB REPEAT, A REMARK 5 SINGLE AMINO ACID INSERTION IN THE TURN IS NEEDED. FOUR REMARK 5 PREDICTED BASE-SPECIFIC RESIDUES (SITE *BSR*, PRESENTED ON REMARK 5 *SITE* RECORDS BELOW) ARE PRESENT ON HELIX 3. THESE REMARK 5 RESIDUES CAN FACE INTO THE MAJOR GROOVE TO BIND TO BASES. REMARK 5 HOWEVER, NOT ALL MAY MAKE DIRECT INTERACTIONS TO BASES. REMARK 6 REMARK 6 THIS MODEL IS FOR A FRAGMENT OF THE MYB PROTEIN. RESIDUE REMARK 6 VAL 1 OF THE MODEL IS RESIDUE VAL 142 OF THE C-MYB AMINO REMARK 6 ACID SEQUENCE (GERONDAKIS,S. AND BISHOP,J.M. MOL.CELL. REMARK 6 BIOL., V6, 3677, 1986).
