[A specific complex between a polypeptide in the left helical conformation of polyproline type II and the B-DNA minor groove].
The model of complex formation between polypeptide adopted lefthanded conformation of polyproline II type and minor groove of B-DNA presented. The specific recognition is attained due to possibility of hydrogen bond between Gly NH-group and Thymine O2-group and in addition between Pro CO-group and Guanine NH2-group and between Gly CO-group and Guanine NH2-group. Stereochemical satisfactory of the complex is observed.
