Figure 4.

Structural comparisons of functionally characterized NTF2-like proteins with ActVI-ORFA. (a) shows ribbon diagrams of ActVI-ORFA (blue) and SnoaL (magenta), while (b) shows a close-up view of the internal cavities of the two proteins. The His/Asp dyad residues are labelled in red; all other residue labels match the colouring of the structures. Least-squares fitting was performed using Secondary Structure Matching (SSM) as implemented in Coot. (c) and (d) show the analogous views for the comparison of ActVI-ORFA with ScyDH (orange). Likewise, (e) and (f) show the comparison of ActVI-ORFA with the dehydrochlorinase LinA (lime green). All images were rendered using POVScript+, MolScript and POV-Ray.
