Venom-sweet-venom: N-linked glycosylation in snake venom toxins

Abstract

Protein glycosylation represents one of the most important post-translational events, and is a mean of diversifying a protein without recourse to the genome. The venoms produced by snakes contain an abundance of glycoproteins with N-linked carbohydrates. N-linked glycosylation can ensure the correct folding of important functional domains. Characterization of carbohydrates structures aids in development of human therapeutics by snake venom toxins.
