The combination of PDB and Pymol creates a great tool to visualize protein structures and manipulate them. The structure above is Aldo-Keto Reductase, which is a stress enzyme found in plants. In this view, you can see NADP bound to it in blue, with alpha helices in red and beta sheets in yellow.

The enzyme is very similar to alcohol dehydrogenase in humans. Similar to the human version, this one is also involved with stress management. It’s primary purpose is drought management. It appears that the active site is the beta-barrel like structure in the middle.
