title: [Expression of neurotoxin II from Naja oxiana cobra venom in Escherichia coli in a hybrid form with thioredoxin].
abstract: Neurotoxin II from the venom of cobra Naja oxiana is a short type alpha-neurotoxin, which competitively inhibits nicotinic acetylcholine receptor. The toxin gene was expressed as a construct fused with the thioredoxin gene and the linker encoding the enteropeptidase recognition site and a Met residue between the genes. The fusion protein was mainly cleaved by cyanogen bromide, since enteropeptidase was less effective. The yield of neurotoxin II was 6 mg/l of the bacterial culture. The resulting recombinant protein was identified with native neurotoxin II by its N-terminal analysis, mass spectrometry, and NMR spectroscopy.
