Abstract excerpt

Small proteins are a new and expanding area of research. Many characterized small proteins are composed of a single hydrophobic α-helix, and the functional requirements of their limited amino acid sequence are not well understood. One hydrophobic small protein, CydX, has been shown to be a component of the cytochrome bd oxidase complex in Escherichia coli, and is required for enzyme function. To investigate small...
