β-Glucuronidase triggers extracellular MMAE release from an integrin-targeted conjugate [PDF]

, 2019
A non-internalizing αvβ3 integrin ligand was conjugated to the anticancer drug MMAE through a β-glucuronidase-responsive linker. In the presence of β-glucuronidase, only the conjugate bearing a PEG4 spacer inhibited the proliferation of integrin ...

A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

Insect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

β-Glucuronidase and Arylsulphatase in some Marine Invertebrates of the Canadian Atlantic Coast

, 1970
β-Glucuronidase and arylsulphatase activity in the digestive gland tissue varied widely among 15 invertebrate species examined. β-Glucuronidase activity was highest in three algae-feeding species of Gastropoda, Littorina littorea, L.

Indole bearing thiadiazole analogs: synthesis, β-glucuronidase inhibition and molecular docking study

BMC Chemistry, 2019
Background Indole based thiadiazole derivatives (1–22) have synthesized, characterized by NMR and HREI-MS and evaluated for β-Glucuronidase inhibition. All compounds showed outstanding β-glucuronidase activity with IC50 values ranging between 0.5 ± 0.08 ...

Rifaximin ameliorates memory impairment and Alzheimer's pathological changes in APP/PS1 mice associated with changes in the gut microbiome–bile acids–serum metabolites networks

British Journal of Pharmacology, EarlyView.
Background and Purpose Modifying the brain–gut–microbiota axis has emerged as a promising therapeutic strategy against Alzheimer's disease (AD). Whether rifaximin, a non‐absorbed and non‐systemic antibiotic, can be applied to the treatment of AD remains unexplored.

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

The 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.

Evaluation of the gut microbiome and sex hormones in postmenopausal women with newly diagnosed hormone receptor-positive breast cancer versus healthy women: a prospective case-control study

Journal of Cancer Research and Clinical Oncology
Purpose The functional composition and diversity of the gut microbiome may affect breast cancer risk by modulation of systemic sex hormones. Gut bacteria with β-glucuronidase enzymatic activity may deconjugate estrogens, leading to increased estrogen ...

Rapid Colorimetric Quantification of Lipo-chitooligosaccharides from Mesorhizobium loti and Sinorhizobium meliloti

Molecular Plant-Microbe Interactions, 2002
Nod factors are lipids with a chitinlike headgroup produced by gram-negative Rhizobium bacteria. These lipo-chitooligosaccharides (LCOs) are essential signaling molecules for accomplishing symbiosis between the bacteria and roots of legume plants ...

Crystal structure and biochemical analysis of the polyester‐degrading carboxylesterase SM0281 from the symbiotic legume‐associated rhizobacterium Sinorhizobium (Ensifer) meliloti

The FEBS Journal, EarlyView.
The microbial degradation of synthetic polyesters such as polyethylene terephthalate (PET) is mediated by diverse α/β‐hydrolases, many of which remain poorly characterized. In this study, we investigated the α/β‐hydrolase SM0281 from Sinorhizobium meliloti and found that it exhibits robust carboxylesterase and polyesterase activities toward PET, PCL ...
