Abstract
The photocontrol of polypeptide membrane conformation and functions was studied by using two membrane systems composed of poly (L-glutamic acid) with azobenzene groups and poly (L-glutamic acid) with pararosaniline groups, respectively. The photoresponsive behavior of these membranes can be explained in terms of the cooperative effect between photo-reaction of photochromic groups and the induced acid dissociation of L-glutamic acid groups in their membrane phase.
