The oligosaccharide chains of cobra venom factor are required for complement activation.

To examine the function of the carbohydrate chains of cobra venom factor (CVF), the molecule was enzymatically deglycosylated under non-denaturing conditions with N-glycanase (peptide-N4-(N-acetyl-beta-glucosaminyl) asparagine amidase). The deglycosylation of CVF chains seems to proceed independently of each other, leading to partially deglycosylated… CONTINUE READING
