Abstract
This review surveys the crystal structures between minor groove drugs and oligonucleotides, of which over thirty have now been determined. The various factors that are involved in the observed A/T sequence selectivity of these drugs are examined in structural terms. The roles of, in particular, hydrogen-bond recognition and sequence-dependent groove width, are assessed, and as a consequence the minor groove drugs have been classified into two categories, dependent on the relative roles played by these two factors in sequence recognition. Implications for the recognition of non-A/T sequences are discussed. © 1997 John Wiley & Sons, Inc. Biopoly 44: 105–121, 1997
