Why human telomere DNA fragments fold into different G-quadruplex structures with parallel, hybrid and antiparallel strand orientations depending on the temperature and concentration of cosolutes remains poorly understood. Similarly, the formation of intermediate structures along their folding or intercoversion pathways is not well understood. Here we address these questions by introducing a conceptual framework, based on the global thermodynamic analysis of DSC and CD spectroscopy data, which enables us to provide a detailed description of the topological phase space (phase diagram) of the stability of the human telomere fragment 5′-AGGG(TTAGGG)3-3′ (Tel22). This framework clarifies the driving forces of quadruplex folding and interconversion processes over a wide range of temperatures and ion (K+,Na+) and polyethylene glycol (PEG) concentrations and demonstrates their linkage to the human telomere DNA structural features.
