WebThe extant phylogenetic variability of a given protein contains information about its underlying sequence-fitness landscape, potentially of value to ancestral reconstruction. In extracting such information, it is pertinent to focus on coarse-grained traits of sequence with strong physicochemical bearing on the protein's phenotype. WebComputational protein design or inverse protein folding aims to generate amino acid sequences that fold into an a priori determined structural fold for engineering novel or enhanced biochemistry. For this task, a function describing the fitness landscape of sequences is critical for identifing correct ones that fold into the desired structure.
