Limulus clotting factor B (EC 3.4.21.85) is an enzyme.[1] This enzyme catalyses the following chemical reaction
- Selective cleavage of -Arg98-Ile- bond in limulus proclotting enzyme to form active clotting enzyme
From the hemocyte granules of the horseshoe crabs Limulus and Tachypleus. This enzyme is downstream of Limulus clotting factor C, but upstream of Limulus clotting enzyme.[2]
