Characteristics of EGF-like toxins identified in M. rubra and M. ruginodis venom glands. The lengths of precursor and mature toxin sequences are shown in amino acids, where # denotes the number of AAs, alongside the predicted molecular weights (MW) and isoelectric points (pI) of the mature toxins. Toxins marked with * were detected by proteomic analysis.
