Dimerization interface of Pb INP. A) Cross-section end-on view of the energy-minimized average Pb INP dimeric structure. The protein is shown in cartoon format, with the tyrosine and serine residues that constitute the interface shown in stick format. The SLTA and TQTA active sites of each chain are indicated. The colouring scheme is the same as in Figure 2. B) Top-down view of the Pb INP dimer. The N termini of the a and b chains that constitute the dimer are indicated.
