FIGURE 4. Comparison of structures of apo-BLAP (A), btl-BLAP (B), E. coli BCCP (1BDO) (C), and 1.3 S subunit (D) (1DCZ). The side chains of residues affected by the biotinylation in BLAP are shown in magenta. The side chains of corresponding residues in other proteins are also shown. The side chain of the target lysine is displayed in yellow, and the biotin is displayed in blue.
