Structural and biochemical basis for retinol‐binding protein 4 antagonism by tinlarebant

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Retinol‐binding protein 4 (RBP4) is a member of the lipocalin superfamily that is connected to disease states such as insulin resistance, fatty liver disease and ocular disorders including Stargardt disease. Several retinoid and non‐retinoid antagonists of this protein have been developed for potential clinical use, but none have

PEG400 regulates Falcipain 2 activity through an allosteric mechanism

open access: yesThe FEBS Journal, EarlyView.
Falcipain‐2 can potentially be leveraged as a drug target due to its critical role as a haemoglobinase during the intra‐erythrocytic stage of Plasmodium falciparum. Here, we investigate the regulation of the proteolytic and haemoglobinase activity of falcipain‐2 in the presence of polyethylene glycol.

Structural and thermodynamic analyses of a novel β‐1,2‐glucan binding mode in the ABC transporter solute‐binding protein Chy400_4166 from Chloroflexus aurantiacus

open access: yesThe FEBS Journal, EarlyView.
Cyclic β‐1,2‐glucan (CβG)‐associated solute‐binding protein of type I ABC transporter was originally identified in Chloroflexus aurantiacus, a phototrophic bacterium. Crystal structures in complex with CβGs revealed unique binding modes that are fundamentally distinct from that of the short β‐1,2‐glucooligosaccharides‐binding protein.

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

open access: yesThe FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Structural insights into θ‐type carbonic anhydrases 3 and 4: Tuning the directionality of CO2 hydration in a diatom

open access: yesThe FEBS Journal, EarlyView.
θ‐CA3 from a marine diatom has an N‐terminal transmembrane helix and two homologous catalytic domains. The enzyme functions as a dimer, with active sites formed near the dimer interface. A bicarbonate ion binds on the symmetry axis of the dimer and forms hydrogen bonds with both monomers, thereby activating θ‐CA3 and tuning CO2 hydration activity ...

Conserved dimerization architecture in C‐type lectins from virus‐vector mosquitoes

open access: yesThe FEBS Journal, EarlyView.
C‐type lectins (CTLs) are involved in the detection of viral/microbial carbohydrates. We studied a family of soluble CTLs in the mosquito Aedes aegypti, which acts as a vector for viruses like dengue and Zika. Using crystallography, biophysics, and structure prediction approaches, we found that these proteins consistently pair together in the same ...
