beta-Furfuryl-beta-glucoside. An endogenous activator of higher plant UDP-glucose: (1—-3)-beta-glucan synthase

Susceptibility of UDP-Glucose:(1,3)-beta-Glucan Synthase to Inactivation by Phospholipases and Trypsin.

UDP-glucose:(1,3)-beta-glucan synthase from Beta vulgaris L. was rapidly inactivated by treatment with phospholipases C, D, and A(2). Enzyme activity could not be restored to the phospholipase-treated enzyme by the addition of phosphatidylethanolamine or other phospholipids. Membrane-bound and solubilized glucan synthase were also trypsin-labile with inactivation rates equal in the presence or ...

Inhalation of (1-->3)-beta-D-glucan causes airway eosinophilia.

BACKGROUND Moulds are present in a variety of environments and aerosols of fungal spores are generated when mouldy materials are handled. Molds contain (1-->3)-beta-D-glucan, a polyglucose which is present in the cell wall of fungi, certain bacteria and plants. AIM This study was undertaken to investigate the cellular inflammatory response in the lung after inhalation of (1-->3)-beta-D-glucan...

Mitochondrial Toxicity of Depleted Uranium: Protection by Beta-Glucan

Considerable evidence suggests that mitochondrial dysfunction contributes to the toxicity of uranyl acetate (UA), a soluble salt of depleted uranium (DU). We examined the ability of the two antioxidants, beta-glucan and butylated hydroxyl toluene (BHT), to prevent UA-induced mitochondrial dysfunction using rat-isolated kidney mitochondria. Beta-glucan (150 nM) and BHT (20 nM) attenuated UA-indu...
