EC 3.4.24.74 Details
EC number
3.4.24.74
Accepted name
fragilysin
Reaction
Broad proteolytic specificity, bonds hydrolysed including -Gly┼Leu-, -Met┼Leu-, -Phe┼Leu-, -Cys┼Leu-, Leu┼Gly
Other name(s)
Bacteroides fragilis (entero)toxin
CAS registry number
188596-63-6
Comment
Thought to be a cause of diarrhoea in animals and humans. Hydrolyses extracellular matrix proteins, and disrupts tight junctions of intestinal epithelial cells. Also degrades intracellular, cytoskeletal proteins actin, myosin and others. In peptidase family M10 (interstitial collagenase family)
