Descripción general
Research area: IMMUNO AND CKS. Biliverdinreductase A (BVRA) is an isozyme of the biliverdin reductase. It is a cellsurface membrane receptor. BVRA consists of two major regions, theregulatory/DNA interaction domain and catalytic domain.
Aplicación
Biliverdin Reductase Ahuman has been used as a component of the incubation medium to evaluate theactivity of hemeoxygenase 1. It has also been used as a standard todetermine the age of the bleed from haemorrhagic lesion.
Acciones bioquímicas o fisiológicas
Biliverdin reductase catalyzes the transformation of the blue-green pigment biliverdin IX to the yellow-orange bile pigment bilirubin IX by converting a double-bond between the second and third pyrrole ring into a single-bond. This enzyme has two distinct cofactor-dependent pH optima. In the acidic range of pH 6.0-6.7, NADH is utilized, whereas in the alkaline range of pH 8.5-8.7, NADPH is utilized. Biliverdin reductase is considered a major physiologic cytoprotectant. Biliverdin reductase suppresses experimental autoimmune encephalomyelitis in rats. Depletion of biliverdin reductase leads to accumulation of cellular oxidants and augmented cell death.Biliverdin reductase (BVR)modulates the functions of insulin via the insulin-like growth factor 1 (IGF-1)pathway. It shows dual specificity kinases where it phosphorylates tyrosineapart from serine and threonine. BVR acts as a biomarker in certain cancers.
Definición de unidad
1 unit of biliverdin reductase will transform 1 nanomole of biliverdin to bilirubin per minute in an NADPH dependent reaction at pH 8.5 using 100 mM K-phosphate buffer at 37 °C.
Forma física
Solution containing 20 mM potassium phosphate buffer, 10% glycerol, 0.2% Igepal CA630, 1 mM EDTA, and 0.1 mM DTT.

Heme oxygenase 1 (HO-1) is induced in response to cellular stress and is responsible for converting the prooxidant heme molecule into equimolar quantities of biliverdin (BV), carbon monoxide (CO), and iron. BV is then converted to bilirubin (BR) by the

Oxidative stress plays an important role in the pathogenesis of multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis (EAE). Bilirubin is regarded today as a potent antioxidant. Recent studies show that the potent antioxidant actions of bilirubin reflect an

Three periplasmic nucleoside monophosphate-splitting phosphatases from Salmonella typhimurium, 2':3'-cyclic nucleotide 2'-phosphodiesterase, nonspecific acid phosphatase I, and nonspecific acid phosphatase II, were separated by column chromatography. They are characterized with respect to their substrate specificities, Km values, pH optima, molecular weights

Chronic inflammation and oxidative stress (OS) are present in Alzheimer's disease (AD) brains in addition to neuronal loss, Amyloid-β (Aβ) plaques and hyperphosphorylated tau-protein neurofibrillary tangles (NFTs). Previously we showed that levels of the pro-inflammatory cytokine, interleukin-18 (IL-18), are elevated
