(a) Overall structure of OsMDHAR. The FAD, NAD, and C-terminal domains are coloured as cyan, light blue, and light pink, respectively. Specifically, the unique long loop is highlighted as blue. The bound FAD, NAD, and AsA molecules are presented as a stick model. (b) Topology diagram of OsMDHAR. The same colour scheme used for panel (a) was applied.
