Proteome‐Wide Target Identification Using Reactive Metallo‐Scaffolds (r‐mS): A Platform for Metallodrug Discovery

open access: yesAngewandte Chemie, EarlyView.
Re‐envisioning the Ligandable Proteome: Reactive Metallo‐Scaffolds (r‐mS) combine non‐covalent protein engagement by a metallo‐scaffold with covalent cysteine capture through a tethered chloroacetamide warhead. Chemoproteomic profiling reveals unique enzyme engagement including ligases, kinases and methyltransferases, highlighting opportunities for ...

A Synthetic β‐Mannan Epitope Enables Immunization and Detection of Candida auris

open access: yesAngewandte Chemie, EarlyView.
A synthetic β‐mannan epitope enables both active and passive immunization against Candida auris. Conjugation to the carrier protein CRM197 induces protective antibody responses, while monoclonal antibodies targeting the same epitope support detection using a lateral flow assay, linking glycochemistry with antifungal prevention and diagnostics ...

Extremal Rees algebras

open access: yesJournal of Commutative Algebra, 2013
We study almost complete intersections ideals whose Rees algebras are extremal in the sense that some of their fundamental metrics---depth or relation type---have maximal or minimal values in the class. The focus is on those ideals that lead to almost Cohen--Macaulay algebras and our treatment is wholly concentrated on the nonlinear relations of the ...
