Abstract: This patent application relates to hybrid and/or single-chain rare-cutting endonucleases, called meganucleases, which recognized and cleave a specific nucleotide sequence, to polynucleotide sequences encoding for said rare-cutting endonucleases, to a vector comprising one of said polynucleotide sequences, to a cell or animal non-human comprising one of said polynucleotide sequences or said rare-cutting endonucleases, to a process for producing one of said rare-cutting endonucleases and any use of the disclosed products and methods. More particularly, this invention contemplates any use of such rare-cutting endonuclease for genetic engineering and gene therapy.

Abstract: The present invention rapidly and efficiently provides proteins engineered to bind to arbitrary target proteins requiring only knowledge of the amino acid sequences of short portions of the target proteins (for example, either the amino or the carboxy termini). This invention provides such proteins as well as methods and systems for their design, synthesis and use, and especially provides for use of a plurality of binding proteins in array format. The engineering methods of the present invention take a precursor protein known to already bind to a short peptide and engineer alterations in precursor proteins so that it binds to a new target peptide by using computer-assisted molecular design techniques and optional assay for actual binding. The invention also provides arrays and libraries of binding proteins and methods of using binding proteins.

Abstract: The present invention relates to a system and method for engineering and designing a macromolecule. An experimentally determined or de novo atomic structure that corresponds to the macromolecule is identified. The atomic structure is composed of building blocks. When the macromolecule is a peptide or a protein, the building blocks are amino acid residues. A target subset of the building blocks in the atomic structure to be optimized is identified. The coordinates of those building blocks that are not in the target subset are fixed. For each building block in the target subset, a large number of potential conformers is sample d. Each conformer to be sampled is substituted into the atomic structure and tested against an energy function that includes the equivalent energy of the conformer in a reference state. Combinations of conformers that best satisfy an interaction energy function are identified.
