Published: February 2024

We have developed a catalytic protocol for Diels-Alder reaction using trialkylphosphonium oxoborates as oxyanion hole catalysts. The reaction can be operated under ambient conditions. Dienes could easily polymerize under acidic condition. Nonetheless, these acid-sensitive substrates are compatible with the catalytic protocol and the reaction scope covers a wide range of substrates.

Article Synopsis
  • PHB (Poly((R)-3-hydroxybutyrate)) is a biodegradable biopolymer used in plastics, and its breakdown is facilitated by an enzyme called PhaZ.
  • Researchers discovered a new version of this enzyme from Bacillus thuringiensis (BtPhaZ) and determined its crystal structure, which is previously uncharacterized for an intracellular PhaZ.
  • BtPhaZ shows structural similarities to other hydrolase enzymes and has specific features that help it bind to and break down PHB, mainly producing monomers rather than longer chains.

The nucleophile elbow is a well-known structural motif, which exists in proteins with catalytic triads and contains a catalytic nucleophile and the first node of an oxyanion hole. Here, we show that structural similarities of proteins with the nucleophile elbow extend beyond simple nucleophile elbow motifs. The motifs are incorporated into larger conserved structural organizations, the ElbowFlankOxy networks, incorporating motifs and flanking residues and networks of conserved interactions.
