Abstract
Scorpion venoms metalloproteinase is involved in a number of important biological, physiological and pathophysiological processes. In this work, a complete sequence of metalloproteinase was first obtained from venom of scorpion Buthus martensi and named as BumaMPs1. BumaMPs1 has 393 amino acid residues containing with a molecular mass of 44.53 kDa, showing an isoelectric point of 5.66. The primary sequence analysis indicated that the BumaMPs1 contains a zinc-binding motif (HELGHNLGISH), methionine-turn motif (YIM), disintegrin-like domain (ETCD) and N-glycosylation site. The multiple alignment of its deduced amino acid sequence and those of other metalloproteinase showed a high structural similarly, mainly among class reprolysin proteases. The phylogenetic analysis showed early divergence and independent evolution of BumaMPs1 from other metalloproteinase.
