Synthetic dityrosine-linked β-amyloid dimers form stable, soluble, neurotoxic oligomers
Dityrosine-linked Aβ dimers have been synthesized and display decreased rates of fibrilization and increased neuronal cell toxicity compared with the corresponding monomeric peptides.
Specific recognition of DNA depurination by a luminescent terbium(III) complex
A terbium(III) complex exhibits sensitive luminescence response to purine bases in DNA, which can be used to recognize DNA depurination as a selective time-resolved luminescence probe.
Responsive MR-imaging probes for N-methyl-D-aspartate receptors and direct visualisation of the cell-surface receptors by optical microscopy
MR Imaging probes for NMDA receptors on a hybrid NSC-34 cell line show relaxation enhancements; the receptors have been visualised by microscopy and the specificity and reversibility of binding demonstrated.
cyclic peptide inhibitor of C-terminal binding protein dimerization links metabolism with mitotic fidelity in breast cancer cells
A cyclic peptide inhibitor of the CtBP transcription repressor, discovered using a genetically encoded HTS platform, is used to link upregulated glycolytic flux to cell-cycle regulation in tumors.
Chemical fidelity of an RNA polymerase ribozyme
We challenge a polymerase ribozyme with an array of nucleotide variants to assess its tolerance of substrate heterogeneity. We uncover specificity determinants, and describe the implications for primordial RNA replication.
hydroxylation of primary carbons in small alkanes by wild-type cytochrome P450BM3 containing perfluorocarboxylic acids as decoy molecules
Primary carbons of propane and ethane are hydroxylated under high-pressure conditions of the alkanes (0.5 MPa) by wild-type P450BM3.
Remodeling a β-
We apply the Rosetta algorithm to repack the hydrophobic core of a β-peptide bundle while retaining both structure and stability.
inhibitors to probe the active site microenvironment of fatty acid amide hydrolase
To test the hypothesis that FAAH recruits its hydrophobic substrates directly from the cellular lipid bilayer, we have created clickable, photoreactive inhibitors that enable exploration of the enzyme's active site microenvironment in native cellular membranes.
