Seiya Watanabe et al. report the crystal structures of two distinct members of the Aconitase X subfamily, which contain [Fe-S] clusters different from other aconitases. This study provides insight into the molecular evolution of the aconitase superfa

In bioconjugation chemistry, achieving a target-specific reaction for a non-modified amino acid is challenging. Here, we report a novel nucleobase-involved native chemical ligation (NbCL) that allows a site-specific oligonucleotide-peptide conjugatio

Aconitase superfamily members catalyze the homologous isomerization of specific substrates by sequential dehydration and hydration and contain a [4Fe-4S] cluster. However, monomeric and heterodimeric types of function unknown aconitase X (AcnX) have

A stopped-flow-electron paramagnetic resonance (EPR) method was applied for the detection of short-lived radicals of flavonoids bearing a catechol moiety as the B-ring, such as flavonols (quercetin, fisetin, and rutin), flavanones (eriodictyol and ta
