Decarboxylation‐Initiated Intermolecular Carbon‐Heteroatom Bond Formation

Protein cross-linking by self-assisted intermolecular disulfide bond formation.

Storage of proteins is a physiological means to provide a reservoir for regulated utilization by the organism. Examples are the intracellular storage of exportable proteins in secretion granules, e.g., in exocrine glands, and the extracellular deposition of secretory proteins, e.g., of thyroglobulin (TG) in the lumina of thyroid follicles. In all cases, tight packaging of protein molecules is o...

Cross-dehydrogenative coupling for the intermolecular C–O bond formation

The present review summarizes primary publications on the cross-dehydrogenative C-O coupling, with special emphasis on the studies published after 2000. The starting compound, which donates a carbon atom for the formation of a new C-O bond, is called the CH-reagent or the C-reagent, and the compound, an oxygen atom of which is involved in the new bond, is called the OH-reagent or the O-reagent....

Nonself recognition through intermolecular disulfide bond formation of ribonucleotide reductase in neurospora.

Type I ribonucleotide reductases (RNRs) are conserved across diverse taxa and are essential for the conversion of RNA into DNA precursors. In Neurospora crassa, the large subunit of RNR (UN-24) is unusual in that it also has a nonself recognition function, whereby coexpression of Oak Ridge (OR) and Panama (PA) alleles of un-24 in the same cell leads to growth inhibition and cell death. We show ...

Spontaneous intermolecular amide bond formation between side chains for irreversible peptide targeting.

Peptides and synthetic peptide-like molecules are powerful tools for analysis and control of biological function. One major limitation of peptides is the instability of their interactions with biomolecules, because of the limited accessible surface area for noncovalent interactions and the intrinsic flexibility of peptides. Peptide tags are nonetheless fundamental for protein detection and puri...
