Controlled Delivery and Light‐Induced Release of Magic Spot Nucleotides in Escherichia coli

Angewandte Chemie International Edition, EarlyView.
We synthesized photocaged, clickable and isotope‐labeled “magic spot” Nucleotides and delivered them into Escherichia coli comparing different approaches. Light‐controlled release inside living cells enabled tracking of their conversion from pppGpp to ppGpp by capillary electrophoresis mass spectrometry and revealed their impact on the growth rate of a

o‐Terphenyl‐Based Family of Conjugated Macrocycles: Selective Recognition of Phenylalanine in Water and Interaction With Insulin

Angewandte Chemie International Edition, EarlyView.
This study presents the synthesis and binding properties of a new family of o‐terphenyl‐based macrocycles, TP[n] (n = 2‐8). The trimer variant efficiently binds phenylalanine in water with a 10‐fold selectivity compared to other amino acids and aromatic neurotransmitters.

Multimodal Chromatography in the Downstream Processing of mAb‐Based Products: Mechanisms, Strategies, and Applications

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Multimodal chromatography has emerged as a powerful tool for the purification of monoclonal antibodies (mAbs) and their derivatives—including antibody fragments (Fabs), Fc‐fusions, bispecific (BsAb), and antibody–drug conjugates (ADCs)—offering enhanced selectivity through the integration of ionic, hydrophobic, hydrogen‐bonding, and π–π ...

Hidden O‐Deglycosylation Activity Triggers O → C Rearrangement for Aryl Di‐C‐Glucoside Formation by the C‐Glycosyltransferase From Fortunella crassifolia

Biotechnology and Bioengineering, EarlyView.
Here, we uncovered an unexpected O‐deglycosylation activity of the C glycosyltransferase (FcCGT), forming phloretin (1) from phloretin 2'‐O‐glucoside (2). In the presence of UDP, FcCGT catalyzes the O→C rearrangement to yield nothofagin (3). Upon additional UDP‐glucose, further C‐glycosylation occurs, forming phloretin 3',5'‐di‐C‐glucoside (4 ...
