Figure 2
Overall structure of the (R)-selective amine transaminase from A. fumigatus viewed normal to the molecular dyad. The subunits of the homodimer are shown in blue and red, respectively. The monomer is divided into colour-coded domains: the small domain (blue, red) with the active-site loop (yellow) and the large domain (cyan, orange). The active-site loop derived from the left subunit is shown in yellow (with Arg126 as a stick model). The cofactor PLP is bound to Lys179 at the domain interface (shown as a stick model in pink). |
