'''SOLUTION STRUCTURE OF THE COVALENT DUOCARMYCIN A-DNA DUPLEX COMPLEX'''<br />


==Overview==
==SOLUTION STRUCTURE OF THE COVALENT DUOCARMYCIN A-DNA DUPLEX COMPLEX==
Duocarmycin A is an antitumour antibiotic that binds covalently to the, minor groove N-3 position of adenine with sequence specificity for the, 3'-adenine in a d(A-A-A-A) tract in duplex DNA. The adenine ring becomes, protonated on duocarmycin adduct formation resulting in charge, delocalization over the purine ring system. We report on the solution, structure of duocarmycin A bound site specifically to A12 (designated, *A12+) in the sequence context d(T3-T4-T5-T6).d(A9-A10-A11-*A12+) within a, hairpin duplex. The solution structure was solved based on a combined, NMR-molecular dynamics study including NOE based intensity refinement. The, A and B-rings of duocarmycin are positioned deep within the walls of the, minor groove with the B-ring (which is furthest from the covalent linkage, ...
