Deletion mutations in N-terminal alpha1 helix render heat labile enterotoxin B subunit susceptible to degradation.


Heat-labile enterotoxin (LT) from enterotoxigenic Escherichia coli is a heterohexameric protein consisting of an enzymatically active A subunit, LTA, and a carrier pentameric B subunit, LTB. It is clear from the crystal structure of LTB that the N-terminal alpha1 helix lies outside the core structure. However, the function of the N-terminal alpha1 helix of… (More)
