Immunogenic Properties of Recombinant Enzymes from Bothrops Ammodytoides Towards the Generation of Neutralizing Antibodies against Its Own Venom.

ABSTRACT: Bothropic venoms contain enzymes such as metalloproteases, serine-proteases, and phospholipases, which acting by themselves, or in synergism, are the cause of the envenomation symptoms and death. Here, two mRNA transcripts, one that codes for a metalloprotease and another for a serine-protease, were isolated from a Bothrops ammodytoides venom gland. The metalloprotease and serine-protease transcripts were cloned on a pCR^®2.1-TOPO vector and consequently expressed in a recombinant way in E. coli (strains Origami and M15, respectively), using pQE30 vectors. The recombinant proteins were named rBamSP_1 and rBamMP_1, and they were formed by an N-terminal fusion protein of 16 amino acid residues, followed by the sequence of the mature proteins. After bacterial expression, each
