Figure 4
Cα-atom superposition of AlrAba and other alanine racemases. Colouring is as follows: A. baumannii, green; P. aeruginosa, red; B. henselae, blue; E. coli, orange. Cα-atom traces showing superposition between the (a) N-terminal and (b) C-terminal domains. (c) Superposition of the N-terminal α/β-barrel domain of whole alanine racemase monomers visualized as a ribbon representation. The PLP cofactor of AlrAba is depicted as a black ball-and-stick model. The difference in inter-monomer hinge angle between the enzymes is indicated by a black double-headed arrow. This figure was produced in PyMOL (DeLano, 2002). |
