Ensemble refinement shows conformational flexibility in crystal structures of human complement factor D

, 2014
Human factor D (FD) is a self-inhibited thrombin-like serine proteinase that is critical for amplification of the complement immune response. FD is activated by its substrate through interactions outside the active site.

Snf2 family ATPases and DExx box helicases:differences and unifying concepts from high-resolution crystal structures [PDF]

, 2006
Proteins with sequence similarity to the yeast Snf2 protein form a large family of ATPases that act to alter the structure of a diverse range of DNA-protein structures including chromatin. Snf2 family enzymes are related in sequence to DExx box helicases,
