There are different glycosylated proteins in snake venoms, but no glycosylated representatives of a large family of three-fingered toxins have previously been detected. A new glycoprotein was isolated from the venom of the Thai cobra Naja kaouthia. MALDI MS of the glycoprotein contained an array of peaks in the range from 8900 to 9400 Da indicating its microheterogeneity. Carbohy-drate analysis showed the presence of mannose, galactose, N-acetylglucosamine, fucose and neuraminic acid.
