A template having four cysteines with selectively detachable protectin
g groups was developed, which enables selective introduction of indivi
dual helices by chemical ligation between the free sulfhydryl group on
the template and the chloroacetyl moiety of the helical peptide. Usin
g the template, a protein having ion channel activity with rectificati
on was obtained. (C) 1997 Elsevier Science Ltd.
