Structural basis of SIRT7 nucleosome engagement and substrate specificity

Henning Paul-Julius Stahlberg, Beat Fierz, Dongchun Ni, Carlos Moreno Yruela, Babatunde Edukpe Ekundayo

Chromatin-modifying enzymes target distinct residues within histones to finetune gene expression profiles. SIRT7 is an NAD+-dependent deacylase often deregulated in cancer, which deacetylates either H3 lysine 36 (H3K36) or H3K18 with high specificity withi ...

Identification of a binding site for small molecule inhibitors targeting human TRPM4

Henning Paul-Julius Stahlberg, Dongchun Ni, Babatunde Edukpe Ekundayo

Transient receptor potential (TRP) melastatin 4 (TRPM4) protein is a calcium-activated monovalent cation channel associated with various genetic and cardiovascular disorders. The anthranilic acid derivative NBA is a potent and specific TRPM4 inhibitor, but ...

Arrestin recognizes GPCRs independently of the receptor state

Henning Paul-Julius Stahlberg, Dongchun Ni, Meltem Tatli

Only two nonvisual arrestins recognize many hundreds of different, intracellularly phosphorylated G protein-coupled receptors (GPCRs). Due to the highly dynamic nature of GPCR•arrestin complexes, the critical determinants of GPCR–arrestin recognition have ...

Structure-function analysis of the cyclic β-1,2-glucan synthase from Agrobacterium tumefaciens

Henning Paul-Julius Stahlberg, Dongchun Ni

The synthesis of complex sugars is a key aspect of microbial biology. Cyclic beta-1,2-glucan (C beta G) is a circular polysaccharide critical for host interactions of many bacteria, including major pathogens of humans (Brucella) and plants (Agrobacterium). ...

Modulation of ABCG2 Transporter Activity by Ko143 Derivatives

Henning Paul-Julius Stahlberg, Dongchun Ni

ABCG2 is a multidrug transporter that protects tissues from xenobiotics, affects drug pharmacokinetics, and contributes to multidrug resistance of cancer cells. Here, we present tetracyclic fumitremorgin C analog Ko143 derivatives, evaluate their in vitro ...

Structural Basis of the Allosteric Inhibition of Human ABCG2 by Nanobodies

Henning Paul-Julius Stahlberg, Dongchun Ni

ABCG2 is an ATP-binding cassette transporter that exports a wide range of xenobiotic compounds and has been recognized as a contributing factor for multidrug resistance in cancer cells. Substrate and inhibitor interactions with ABCG2 have been extensively ...

Activation mechanism of a short argonaute-TIR prokaryotic immune system

Henning Paul-Julius Stahlberg, Dongchun Ni, Babatunde Edukpe Ekundayo

Short prokaryotic argonaute (pAgo) and toll/interleukin-1 receptor/resistance protein (TIR)-analog of PAZ (APAZ) form a heterodimeric SPARTA complex that provides immunity to its prokaryotic host through an abortive infection mechanism. Monomeric SPARTA se ...

Structure of a membrane-bound menaquinol:organohalide oxidoreductase

Christof Holliger, Henning Paul-Julius Stahlberg, Julien Maillard, Dongchun Ni, Babatunde Edukpe Ekundayo, Lorenzo Cimmino

Organohalide-respiring bacteria are key organisms for the bioremediation of soils and aquifers contaminated with halogenated organic compounds. The major players in this process are respiratory reductive dehalogenases, corrinoid enzymes that use organohali ...
