We have used the occluded surface algorithm to estimate the packing of both buried and exposed amino acid residues in protein structures. This method works equally well for buried residues and solvent-exposed residues in contrast to the commonly used

Methylene is one of, if not the, most reactive organic chemical known. It has a very low specificity, which makes it essentially useless for synthesis, but suggests a possible role in protein footprinting with special importance in labeling solvent a

The structures of several variants of staphylococcal nuclease with long flexible unnatural amino acid side chains in the hydrophobic core have been determined by X-ray crystallography. The unnatural amino acids are disulfide moieties between the lone

The reduction of disulfides by thioredoxin involves a two-step mechanism. The first step features an intermolecular attack of Cys32 of thioredoxin on the disulfide with formation of a protein mixed disulfide and release of 1 equiv of thiol. The secon

The Src-homology-3 (SH3) domains of the Caenorhabditis elegans protein SEM-5 and its human and Drosophila homologues, Grb2 and Drk (refs 1-4), bind proline-rich sequences found in the nucleotide-exchange factor Sos as part of their proposed function

Two fragments of pancreatic ribonuclease A, a truncated version of S-peptide (residues 1-15) and S-protein (residues 21-124), combine to give a catalytically active complex. We have substituted the wild-type residue at position 13, methionine (Met),

Src homology 3 (SH3) domains bind specific proline-rich peptide motifs. To identify interactions involved in peptide recognition, we have mutated residues on the putative binding surface of an SH3 domain from the Caenorhabditis elegans protein Sem-5.

Previously, we have introduced a method whereby novel disulfide side chains can be produced in the interior of a protein by modifying a cysteine residue after denaturant-induced unfolding [Wynn, R., & Richards, F. M. (1993) Proteins: Struct., Funct.,

The number of globular proteins for which high resolution structures are available is rapidly increasing. In each case the particular sequence of the polypeptide appears to yield only a single, compact, biologically active structure. However, peptide
