Crystal Structure and Conformational Dynamics of N─N Bond‐Forming Piperazate Synthase

open access: yesChemBioChem, Volume 27, Issue 12, 26 June 2026.
Piperazate synthases (PZSs) catalyze the key N─N bond formation in the biosynthesis of the rare amino acid piperazic acid. X‐ray crystal structures of apo‐ and holo‐SbPZS show a dimeric enzyme with two heme‐containing active sites, where histidine residues coordinate the iron centers.

Racemisation of Amino Acids: From Synthetic Challenge to Biological Significance

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
Racemisation, once considered an undesirable synthetic side reaction, also occurs naturally in amino acids and influences biological processes. Evidence links stereochemical conversion to ageing, protein turnover, and cellular development. This review examines mechanisms, control strategies in synthesis, applications and implications in physiology ...

Hierarchically Engineered Multi‐Enzyme Nanoreactors for in vitro Drug Biosynthesis and Pathway Transplantation Into Cells

open access: yesAdvanced Materials, Volume 38, Issue 34, 17 June 2026.
A hierarchically structured metal–organic framework (eMIL) is shown to host the complete six‐enzyme biosynthesis pathway for the anti‐cancer pigment violacein, reshaping reaction dynamics and multiplying in vitro yields. eMIL nanoreactors deliver this reconstituted bacterial multi‐protein system into mammalian cells, where cell‐derived substrates and ...

Wave Mechanics of Ciliary Proteins: Quantum‐Enabled Sensing and Energy Transfer in the “Cellular Antenna”

open access: yesAggregate, Volume 7, Issue 6, June 2026.
This review surveys eukaryotic cilia as putative quantum‐enabled sensory and regulatory centers. It highlights their multifaceted roles in the cell, focuses on the nontrivial roles of quantum mechanics in their membrane and cytoskeletal proteins, and introduces the essential building blocks enabling quantum properties to survive in the warm, wet, and ...
