Figure 1
(a) Ribbon representation of the A. baumannii alanine racemase dimer. Monomers are coloured blue and red, with the surface representation of one monomer also shown in blue. The PLP cofactors are depicted as black ball-and-stick models. (b) Structure of the A. baumannii alanine racemase monomer. Ribbon representation with α-helices coloured orange and β-sheets shown in green. The PLP cofactor covalently bound to Lys34 is shown as a black ball-and-stick model. This figure was produced in PyMOL (DeLano, 2002). |
