BLUFSensors of blue-light using FAD
|SMART accession number:||SM01034
||The BLUF domain has been shown to bind FAD in the AppA protein (Q53119). AppA is involved in the repression of photosynthesis genes in response to blue-light.|
|Interpro abstract (IPR007024):
||The BLUF domain (named for sensors of Blue-Light Using FAD) is an FAD-binding protein domain. BLUF domains are present in various proteins, primarily from bacteria. For example a BLUF domain is found at the N terminus of the AppA protein from Rhodobacter sphaeroides [(PUBMED:16323221)]. BLUF domains are involved in sensing blue-light (and possibly redox) using FAD, and are similar to the flavin-binding PAS domains and cryptochromes. Their predicted secondary structure reveals that the BLUF domains have a novel FAD-binding fold [(PUBMED:12368079)].
|GO function:||FAD binding (GO:0071949), blue light photoreceptor activity (GO:0009882)|
There are 1404 BLUF domains in 1384 proteins in SMART's nrdb database.
