Abstract: | A novel FAD-binding domain, BLUF, exemplified by the N-terminus of the AppA protein from Rhodobacter sphaeroides, is present in various proteins, primarily from Bacteria. The BLUF domain is involved in sensing blue-light (and possibly redox) using FAD and is similar to the flavin-binding PAS domains and cryptochromes. The predicted secondary structure reveals that the BLUF domain is a novel FAD-binding fold. |
