Reconstitution of apomyoglobin with extended biliverdins
Biochemical and Biophysical Research Communications, 1992An analysis of the reconstitution of biliverdins with extended conformations and horse heart apomyoglobin was carried out. Biliverdins with the 5Z-syn, 10Z-syn, 15Z-anti and 5Z-anti, 10Z-syn, 15Z-anti conformations, as well as biliverdins with the Z,Z,Z, all-syn conformation recombined with apomyoglobin.

Photodecomposition of bilirubin and biliverdin in vitro
Gastroenterology, 1970Summary Decomposition of bilirubin and biliverdin under intense fluorescent light was studied in vitro at p H levels ranging from 7.4 to 13.0. Photodecay of bilirubin was more rapid at a higher p H if albumin was absent, but more rapid at a lower p H if albumin was present, whereas biliverdin was more stable at a lower p H, with or without albumin.

Biliverdin pigments in green biles
Biochimica et Biophysica Acta (BBA) - General Subjects, 1965Abstract 1. 1. The nature of the green bile pigments in various animal species has been studied using reversed-phase partition chromatography and paper chromatography. 2. 2. The chromatographic behaviour of the pigments has been compared with that of synthetic biliverdin derivatives. 3. 3.

Separation and properties of conjugated biliverdin
Biochimica et Biophysica Acta (BBA) - General Subjects, 1965Abstract 1. 1. Reversed-phase partition chromatography and paper chromatography have been used to separate free biliverdin from conjugated biliverdin. 2. 2. The colour of green post-mortem bile appears to be associated with both biliverdin monoglucuronide and biliverdin diglucuronide. 3. 3.

THE SINGLET OXYGEN REACTIVITY OF BILIVERDIN
Photochemistry and Photobiology, 1977Abstract— In 1, 1, 2‐trichlorotrifluoroethane solution biliverdin physically quenches singlet oxygen at a rate of 8 × l0sM‐1s‐1 and reacts chemically at 6 × 10 5M‐1s‐1 to give a red product. In D, O solution the rate constants are PD dependent and range from 1.5–6 times 1010M‐1s‐1 for quenching and the chemical rate varies from 3–5 × 108 M‐1 s‐1 to ...

THE TRIPLET EXCITED STATES OF BILIVERDIN AND BILIVERDIN DIMETHYL ESTER
Photochemistry and Photobiology, 1979Abstract— The triplet states of biliverdin and biliverdin dimethyl ester have been generated using pulse radiolysis excitation. Biliverdin triplet was formed by energy transfer from biphenyl triplet in acetone, absorbed throughout the wavelength range studied (380–1000 nm) and had a half‐life of 11.7μs under the cpnditions chosen.

The specificity of biliverdin reductase. A study with different biliverdin types.
Biochimica et biophysica acta, 1985The specificity of rat liver biliverdin reductase was examined with the help of a series of synthetic biliverdins. The mixture of the four biliverdin isomers obtained by the chemical oxidation of protohemin I, protohemin XI, protohemin XIV and harderohemin were used as substrates of biliverdin reductase and were compared with the mixture of biliverdins

The specificity of biliverdin reductase. The reduction of biliverdin XIII isomers.
Biochimica et biophysica acta, 1984The 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 ...

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 ...

Cyclization of biliverdins to verdohaemochromes
Journal of the Chemical Society, Perkin Transactions 1, 1986Iron(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 ...
