Tracing the evolutionary history of proteins can reveal insights into gene alterations responsible for changes in structure and function. Here, the origin of snake venom metalloproteinases was rigorously reassessed using phylogenetics and the reconstruction of ancestral sequences. Basal SVMPs are most closely related to ADAM 7, 28 and decysin 1 proteins. Reconstructing the evolutionary history of these proteins and their hypothetical ancestors elucidates progressive alterations in the amino acid composition and structural characteristics of ADAMs/SVMPs through evolutionary time.
