Protein Design (Methods in Molecular Biology)
Format: PDF / Kindle (mobi) / ePub
Protein Design: Methods and Applications presents the most up-to-date protein design and engineering strategies so that readers can undertake their own projects with a maximum chance of success.
The authors present integrated computational approaches that require various degrees of computational complexity, and the major accomplishments that have been achieved in the design and structural characterization of helical peptides and proteins.

Doig Summary The α-helix is the most abundant secondary structure in
well-characterized. This small toxin contains an Design of Bioactive Miniproteins 123 antiparallel β-sheet which is linked in the interior core to an α-helix and an extended segment by three disulfide bridges, leaving the solvent exposed face of the β-sheet available to protein design (see Note 4). 3.1.2. Choice of the Active Site Although the forces that stabilize a metal-protein interaction are not yet fully understood and cannot be treated rigorously yet by ordinary force field
or networks of, interactions present in the alignment. This has been applied to TPRs (29), and it revealed that, although the consensus TPRs are highly negatively charged, the natural sequences are mostly near neutral, often with conserved interaction networks between charged residues, lacking in the consensus sequence. Indeed, engineering one such network to the three repeat consensus TPR protein increased the thermostability significantly, even from the already high value Tm = 83°C to an
