The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

open access: yesThe FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Supramolecular Behaviour of Heterochiral Dipeptides With Ile

open access: yesJournal of Peptide Science, Volume 32, Issue 10, October 2026.
This study describes the supramolecular behaviour and gelation of heterochiral, aliphatic dipeptides d‐Ile‐l‐Xaa (Xaa = Ala, Val, Leu or Ile) in various solvents and buffered water at neutral pH. Metastable gels rapidly crystallised. X‐ray diffraction analysis was conducted to unveil the dipeptides' packing modes in amphipathic layers.

Photocatalytic Synthesis and Palladium‐Catalyzed Functionalizations of Hydrofluoroolefin (HFO‐1234ze)‐Based Vinyl Iodides

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 18, 19 September 2026.
An inexpensive industrial refrigerant, HFO‐1234ze, is transformed into a versatile fluoroalkyl building block via a scalable, solvent‐free protocol. Utilizing the metal‐free photocatalyst 4CzIPN, efficient visible‐light‐induced radical addition to alkynes reveals distinct, substrate‐dependent stereoselectivities.

Unified Synthesis of Unconventional α‐Polyhalogenated Amines Through Hydroaminoalkylation

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 38, 14 September 2026.
A unified, redox‐neutral method that transforms alkenes and alkynes into α‐polyhalomethyl amines using stable hemiaminal reagents is reported. This approach enables access to CF3, CF2H, CF2Cl, and CFClH motifs, expanding halogenated amine space with broad substrate scope, functional group tolerance, and applicability to late‐stage modification of drug ...
