Limulus clotting factor B (EC 3.4.21.85) is an enzyme.[1] This enzyme catalyses the following chemical reaction:
- Selective cleavage of -Arg98-Ile99- bond in limulus proclotting enzyme to form active clotting enzyme
This enzyme is present in the hemocyte granules of the horseshoe crabs Limulus and Tachypleus. In the immunity-related clotting pathways of these organisms, factor B is downstream of Limulus clotting factor C, but upstream of Limulus clotting enzyme.[2]
