Exocellular β-Lactamases of Streptomyces albus G and Strains R39 and K11 [PDF]
Antimicrobial Agents and Chemotherapy, 1973 The β-lactamases excreted by the highly benzylpenicillin-susceptible Streptomyces strain R39 and the highly benzylpenicillin-resistant Streptomyces albus G were isolated and purified. Neither β-lactamase exhibited dd -carboxypeptidase activity. Both were anionic at

DCAF13 Safeguards Hematopoietic Stem Cells via RRS1‐Regulated Ribosome Biogenesis
Advanced Science, EarlyView.This study establishes DCAF13 as an essential regulator for hematopoietic stem cell (HSC) function. Its deletion in mice causes lethal pancytopenia and HSC depletion. Mechanistically, DCAF13 interacts with RRS1 and mediates its non‐degradative K27‐linked ubiquitination, thereby stabilizing RRS1 to maintain ribosome biogenesis and protein translation ...

The four known biplanes with k=11
International Journal of Mathematics and Mathematical Sciences, 1979 The four known biplanes of order 9(k=11) are described in terms of their ovals, λ-chain structures, and automorphism groups. An exhaustive computer search for all biplanes of order 9 with certain chain structures has produced but two, one of which is new.

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis
Advanced Science, EarlyView.Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.

Angewandte Chemie, EarlyView.Diese Studie beschreibt die Herstellung und Eigenschaften einer neuen Familie von o‐Terphenyl‐basierten Makrozyklen, TP[n] (n = 2‐8). Der Trimer bindet Phenylalanin in Wasser sehr effizient und ist dabei zehnmal selektiver als bei anderen Aminosäuren und aromatischen Neurotransmittern.

Multiple E3 ligases control tankyrase stability and function
Nature Communications, 2023 Tankyrase 1 and 2 are ADP-ribosyltransferases that catalyze formation of polyADP-Ribose (PAR) onto themselves and their binding partners. Tankyrase protein levels are regulated by the PAR-binding E3 ligase RNF146, which promotes K48-linked ...

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.
