The specificity of biliverdin reductase. The reduction of biliverdin XIII isomers.

Biochimica et biophysica acta, 1984
The substrate specificity of the different molecular forms of biliverdin reductase (bilirubin:NAD(P)+ oxidoreductase, EC 1.3.1.24) using biliverdin XIII alpha, XIII beta and XIII gamma was examined. It was found that molecular form 1 (the major form in normal rat liver) reduced biliverdin XIII alpha at a much higher rate than the other two isomers ...

Cyclization of biliverdins to verdohaemochromes

Journal of the Chemical Society, Perkin Transactions 1, 1986
Iron(II) octaethylverdohaemochrome was obtained both by cyclization of octaethylbiliverdin in the presence of FeSO4 and pyridine, and by coupled oxidation of octaethylhaemin and ascorbic acid with O2 in the presence of pyridine. The compound obtained by cyclization of biliverdin IXα dimethyl ester was, however, different from that obtained by the ...

Detection of Biliverdin Reductase Activity

Current Protocols in Toxicology, 1999
AbstractThe conversion of biliverdin to the bile pigment bilirubin is catalyzed by biliverdin reductase, a cytosolic enzyme with two pH optima with different cofactors. The enzyme is assayed at pH 8.7 with NADPH as a cofactor and at 6.75 with NADH. The production of bilirubin is detected as described in this unit with a spectrophotometric assay.

Hepatobiliary excretion of biliverdin isomers and C10-substituted biliverdins in Mrp2-deficient (TR−) rats

Biochemical and Biophysical Research Communications, 2002
Multidrug resistance protein 2 (Mrp2) is considered the major mammalian membrane transporter of non-bile salt organic anions from liver to bile. Using Mrp2-deficient rats, we show that the protein is not essential for biliary excretion of biliverdin, its IIIalpha and XIIIalpha isomers, mesobiliverdin XIIIalpha or biliverdins bearing bulky lipophilic ...

The enzymatic and chemical reduction of extended biliverdins

Biochemical and Biophysical Research Communications, 1990
The substrate specificity of rat liver biliverdin reductase was probed using helical and extended biliverdins. The former were the ZZZ-all-syn biliverdins IX alpha and IX gamma, and the latter were the 5Z-syn, 10Z-syn, 15Z-anti; 5Z-anti, 10E-anti, 15E-anti biliverdins.

Biliverdin in Biological Systems

1984
Green pigments were first recognized early in the nineteenth century in canine placenta [1], avian eggshells [2], and in frog’s blood serum after liver extirpation [3]. Its chemical structure remained uncertain until 1932 when Lemberg [4, 5] confirmed its identity as the bilatriene, biliverdin (BV).
