Site‐Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids

open access: yesAngewandte Chemie, EarlyView.
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...

Noncanonical Peloruside A Biosynthesis by an Uncultivated Verrucomicrobiota Symbiont

open access: yesAngewandte Chemie, EarlyView.
Noncanonical biochemistry of the peloruside PKS characterized in this work, comprising double bond generation by a noncanonical tridomain (blue), acetyl‐CoA recycling (orange), and proofreading systems (purple and yellow). The Z‐double bond is installed by TEB1 through O‐acetylation and acetate elimination. The acyl ligase PelB (AL, orange) selectively

Post‐Synthetic Zinc Modifications to Correct Speciation in Ti‐MWW Zeolites for Catalytic Oxidation

open access: yesAngewandte Chemie, EarlyView.
Post‐synthetic Zn modifications of Ti‐MWW zeolite catalysts exhibit improved catalytic properties in the selective oxidation reaction, namely the ammoximation reaction. The origin of the beneficial effect of Zn is related via an array of spectroscopic and microscopic techniques to the modification of extra‐framework TiO2 and TiOx clusters and the ...

Evidence for a Cu(II)‐Catalysed CuAAC Reaction: A Combined Experimental and Computational Study

open access: yesAngewandte Chemie, EarlyView.
A new mechanistic pathway for the CuAAC reaction has been found to operate under specific reaction conditions. The pathway is catalysed by Cu(II) through a self‐assembled dinuclear Cu(II) complex that incorporates the triazole product. Computational analysis and assessment of generality are reported.
