pro-e-Tx1X/12 corresponds to the residues -12 to -1 of the epsilon-conotoxin (ε-TxIX) precursor. The epsilon-TxIX is derived from the venom of the marine snail Conus textile. The propeptide directs gamma-carboxylation of the conotoxin precursor and lowers the apparent Km. Czerwiec, E; et al., Eur. J. Biochem., 269, 6162 (2002).
