This entry represents the C-terminal domain of the TypA/BipA protein. The C-terminal domain of BipA, consisting of residues, forms a unique motif with two crossed beta sheets (comprising of two and four beta-strands, respectively) wrapped by three short alpha helices forming a nearly equilateral triangle [1].
