BILIPROTEINS FROM THE BUTTERFLY Pieris brassicae STUDIED BY TIME-RESOLVED FLUORESCENCE AND COHERENT ANTI-STOKES RAMAN SPECTROSCOPY [PDF]

, 1988
The fluorescence decay time of the biliverdin IX7 chromophore present in biliproteins isolated from Pieris brassicae is determined to be 44 ± 3 ps. This value suggests a cyclic helical chromophore structure. The vibrational frequencies determined by CARS-

Biliverdin incorporation into the cyanobacteriochrome SPI1085g3 from Spirulina

Frontiers in Microbiology, 2022
Cyanobacteriochromes (CBCRs) bind linear tetrapyrrole chromophores, mostly phycocyanobilin (PCB), and exhibit considerable spectral diversity with a high potential for biotechnological applications.

ABCB10 exports mitochondrial biliverdin, driving metabolic maladaptation in obesity [PDF]

, 2021
Although the role of hydrophilic antioxidants in the development of hepatic insulin resistance and nonalcoholic fatty liver disease has been well studied, the role of lipophilic antioxidants remains poorly characterized.

Protocol for the assay of biliverdin by the recombinant protein HUG

, 2022
Biliverdin is a secondary metabolite of heme catabolism. It is formed by the reaction catalyzed by heme oxygenase, which converts the heme group contained in proteins, such as hemoglobin, myoglobin, cytochromes, and catalase, to biliverdin, iron (II ...

Systems metabolic engineering of Corynebacterium glutamicum for the bioproduction of biliverdin via protoporphyrin independent pathway

Journal of Biological Engineering, 2019
Background Biliverdin, a prospective recyclable antioxidant and one of the most important precursors for optogenetics, has received growing attention. Biliverdin is currently produced by oxidation of bilirubin from mammalian bile using chemicals. However,

Research Note: L*a*b* color space for prediction of eggshell pigment content in differently colored eggs

Poultry Science, 2022
: Eggshell color is the most intuitive external feature that affects consumer acceptance. Different eggshell colors are mainly determined by protoporphyrin IX and biliverdin content. The selection of eggshell color by the human eye with an eggshell color

The Role of Bilirubin and the Other “Yellow Players” in Neurodegenerative Diseases

Antioxidants, 2020
Bilirubin is a yellow endogenous derivate of the heme catabolism. Since the 1980s, it has been recognized as one of the most potent antioxidants in nature, able to counteract 10,000× higher intracellular concentrations of H2O2.

Computational Insights Into the Effects of the R190K and N121Q Mutations on the SARS-CoV-2 Spike Complex With Biliverdin

Frontiers in Molecular Biosciences, 2021
The SARS-CoV-2 spike has been regarded as the main target of antibody design against COVID-19. Two single-site mutations, R190K and N121Q, were deemed to weaken the binding affinity of biliverdin although the underlying molecular mechanism is still ...

Breakdown products of heme catabolism as senescence index in sea lamprey (Petromyzon marinus Linnaeus, 1758)

Frontiers in Marine Science, 2015
Biliverdin and bilirubin are breakdown products of normal heme catabolism, caused by the body's clearance of aged red blood cells which contain hemoglobin.
