2013 journal article

Lengthening the Intersubunit Linker of Procaspase 3 Leads to Constitutive Activation

BIOCHEMISTRY, 52(36), 6219–6231.

By: S. MacKenzie n, J. Schipper n, E. England n, M. Thomas n, K. Blackburn n, P. Swartz n, A. Clark n

MeSH headings : Apoptosis / physiology; Caspase 3 / chemistry; Caspase 3 / genetics; Caspase 3 / metabolism; Caspase Inhibitors / pharmacology; Catalytic Domain; Enzyme Activation; Enzyme Precursors / chemistry; Models, Chemical; Models, Molecular; Molecular Dynamics Simulation; Protein Conformation; Protein Multimerization
TL;DR: The data show that releasing the strain of the short IL is not sufficient to populate the active conformer of the native ensemble, and it is shown that increasing the length of the IL by introducing 3-5 alanines results in constitutively active procaspases. (via Semantic Scholar)

2012 journal article

Allosteric modulation of caspase 3 through mutagenesis

BIOSCIENCE REPORTS, 32(4), 401–411.

By: J. Walters n, J. Schipper n, P. Swartz n, C. Mattos n & A. Clark n

author keywords: allosteric site; apoptosis; caspase; inhibition; protein ensemble
MeSH headings : Allosteric Regulation / genetics; Allosteric Site / genetics; Amino Acid Substitution; Caspase 3 / chemistry; Caspase 3 / genetics; Catalytic Domain; Crystallography, X-Ray; Humans; Hydrogen Bonding; Molecular Dynamics Simulation; Mutagenesis, Site-Directed; Protein Interaction Domains and Motifs; Protein Structure, Secondary
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.

2011 journal article

A bifunctional allosteric site in the dimer interface of procaspase-3

BIOPHYSICAL CHEMISTRY, 159(1), 100–109.

By: J. Schipper n, S. MacKenzie n, A. Sharma n & A. Clark n

author keywords: Caspase; Apoptosis; Allosteric activator; Drug design; Cancer therapy
MeSH headings : Allosteric Site; Caspase 3 / chemistry; Caspase 3 / metabolism; Enzyme Activation / drug effects; Humans; Models, Molecular; Protein Binding; Protein Multimerization; Small Molecule Libraries / chemistry; Small Molecule Libraries / pharmacology
TL;DR: This work has utilized the allosteric site of caspase-3 to identify a small molecule activator of procaspase and to characterize its binding to the protease, and suggests that an efficient activator must stabilize the active conformer of the zymogen by expelling the intersubunit linker from the interface.
