Exolytic hydrolysis of toxic plant glucosides by guinea pig liver cytosolic beta-glucosidase.

open access: yesJournal of Biological Chemistry, 1992
We demonstrate that although the guinea pig liver cytosolic beta-glucosidase does not catalyze the hydrolysis of gentiobiose, it does hydrolyze, disaccharide-containing glycosides such as p-nitrophenyl-beta-D-gentiobioside (Glc beta 1----6Glc beta-pNP ...

Foliar particulate matter retention and toxic trace element accumulation of six roadside plant species in a subtropical city

open access: yesScientific Reports, 2023
As a major source of air pollution, particulate matter (PM) and associated toxic trace elements pose potentially serious threats to human health and environmental safety. As is known that plants can reduce air PM pollution.
