Abstract
In biology, supramolecular recognition typically involves an ‘induced-fit’ mechanism, where structures rearrange upon complexation to accommodate binding ligands. Designing minimalistic compounds with such adaptability is challenging as they involve subtle conformational changes that are energetically similar. Here, we demonstrate the integration of combinatorial screening with molecular modelling to identify heptapeptides that form a stable loop upon recognition of uridine triphosphate (UTP). Peptide sequences selected using phage display were refined computationally and correlated with experimental KD values. This combined approach may serve as a method for the de novo selection and subsequent rationalization of the compositional and organizational principles that dictate chemical functionality in flexible structures with dynamic conformations.
