De novo design of a transmembrane Zn²⁺-transporting four-helix bundle.
The design of functional membrane proteins from first principles represents a grand challenge in chemistry and structural biology. Here, we report the design of a membrane-spanning, four-helical bundle that transports first-row transition metal ions Zn(2+) and Co(2+), but not Ca(2+), across membranes. The conduction path was designed to contain two di-metal binding sites that bind with negative...
متن کاملDe novo design, expression, and characterization of Felix: a four-helix bundle protein of native-like sequence.
The protein Felix was designed de novo to fold into an antiparallel four-helix bundle of specific topology. Its sequence of 79 amino acid residues is not homologous to any known protein sequence, but is "native-like" in that it is nonrepetitive and contains 19 of the 20 naturally occurring amino acids. Felix has been expressed from a synthetic gene cloned in Escherichia coli, and the protein ha...
متن کاملDe novo design of the hydrophobic cores of proteins.
We have developed and experimentally tested a novel computational approach for the de novo design of hydrophobic cores. A pair of computer programs has been written, the first of which creates a "custom" rotamer library for potential hydrophobic residues, based on the backbone structure of the protein of interest. The second program uses a genetic algorithm to globally optimize for a low energy...
متن کاملDe novo enzymes by computational design.
Computational enzyme design has emerged as a promising tool for generating made-to-order biocatalysts. In addition to improving the reliability of the design cycle, current efforts in this area are focusing on expanding the set of catalyzed reactions and investigating the structure and mechanism of individual designs. Although the activities of de novo enzymes are typically low, they can be sig...
متن کاملProtein architecture by de novo design
De novo protein design is an essential approach to elucidate the principles of protein structure and has potential applications that can yield novel molecules for medical and industrial purposes, such as drug discovery. The new idea that we can design artificial amino-acid sequences capable of folding into the desired three-dimensional (3D) structure may originate from the conceptual proposal m...
