Phage display and structural studies reveal plasticity in substrate specificity of caspase-3a from zebrafish
Protein Science, 25(11), 2076–2088.
Contributors: M. Tucker n, S. MacKenzie n, J. Maciag n, H. Dirscherl Ackerman, n, J. Yoder n , P. Hamilton n , A. Clay Clark *
author keywords: phage display substrate library; substrate recognition; Danio rerio; apoptosis
MeSH headings : Allosteric Regulation; Animals; Caspase 3 / chemistry; Crystallography, X-Ray; Molecular Dynamics Simulation; Peptide Library; Substrate Specificity; Zebrafish
TL;DR:
The structure of zebrafish Casp3a is determined to 2.28Å resolution by X‐ray crystallography, and the results suggest that a limited number of amino acid substitutions near the active site result in plasticity of the S4 sub‐site by increasing flexibility of one active site loop and by affecting hydrogen‐bonding with substrate.

Allosteric modulation of caspase 3 through mutagenesis
BIOSCIENCE REPORTS, 32(4), 401–411.
author keywords: allosteric site; apoptosis; caspase; inhibition; protein ensemble

TL;DR:
The results demonstrate that considering allosteric inhibition of caspase 3 as a shift between discrete ‘off-state’ or ‘on- state’ conformations is insufficient and requires the representation of an ensemble of inactive states and shows that subtle structural changes lead to the population of the inactive ensemble.

Thermodynamic, enzymatic and structural effects of removing a salt bridge at the base of loop 4 in (pro)caspase-3
ARCHIVES OF BIOCHEMISTRY AND BIOPHYSICS, 508(1), 31–38.
