Abstract

Whereas heat capacity changes (Δ__C~P~__s) associated with folding transitions are commonplace in the literature of protein folding, they have long been considered a minor energetic contributor in nucleic acid folding. Recent advances in the understanding of nucleic acid folding and improved technology for measuring the energetics of folding transitions have allowed a greater experimental window for measuring these effects. We present in this review a survey of current literature that confronts the issue of Δ__C~P~__s associated with nucleic acid folding transitions. This work helps to gather the molecular insights that can be gleaned from analysis of Δ__C~P~s and points toward the challenges that will need to be overcome if the energetic contribution of Δ__C~P~ terms are to be put to use in improving free energy calculations for nucleic acid structure prediction. © 2006 Wiley Periodicals, Inc.
