Crystallization and preliminary X‐ray analysis of a PNA‐DNA complex

Abstract
Peptide nucleic acids (PNAs) are DNA mimics with a peptide backbone. PNAs are being intensely investigated owing to a potential as gene-targeted drugs. A PNA (H-GTAGAT-CACT-NH 2 )-DNA (5′-AGTGATCTAC-3′) complex has been crystallized in a tetragonal space group P4 1 22 with cell dimensions a = b = 79.8, c = 99.9 A ̊ . The crystals diffract to about 5 Å resolution.
