Evidence for Participation of Remote Residues in the Catalytic Activity of Co-type Nitrile Hydratase from Pseudomonas putida
Biochemistry
Active sites may be regarded as layers of residues, whereby the residues that interact directly with substrate also interact with residues in a second shell, and these in turn interact with residues in a third shell. These residues in the second and ...

Distribution of glutamine and asparagine residues and their near neighbors in peptides and proteins.
Proc Natl Acad Sci U S A
In a statistical study of neighboring residues in 1465 peptides and proteins comprising 450,431 residues, it was found that the preferences for residues neighboring to glutamine and asparagine residues are consistent with the hypothesis that the rate...

Implication of Terminal Residues at Protein-Protein and Protein-DNA Interfaces
PLoS One
Terminal residues of protein chains are charged and more flexible than other residues since they are constrained only on one side. Do they play a particular role in protein-protein and protein-DNA interfaces? To answer this question, we considered la...

Studies on tryptophan residues of Abrus agglutinin. Stopped-flow kinetics of modification and fluorescence-quenching studies.
Biochem J
The presence of two essential tryptophan residues/molecule was implicated in the binding site of Abrus agglutinin [Patanjali, Swamy, Anantharam, Khan & Surolia (1984) Biochem. J. 217, 773-781]. A detailed study of the stopped-flow kinetics of the...

On the Structural Context and Identification of Enzyme Catalytic Residues
Biomed Res Int
Enzymes play important roles in most of the biological processes. Although only a small fraction of residues are directly involved in catalytic reactions, these catalytic residues are the most crucial parts in enzymes. The study of the fundamental an...

Autonomous aggregation suppression by acidic residues explains why chaperones favour basic residues
EMBO J
Many chaperones favour binding to hydrophobic sequences that are flanked by basic residues while disfavouring acidic residues. However, the origin of this bias in protein quality control remains poorly understood. Here, we show that while acidic resi...
