Cofactor-free light-driven whole-cell cytochrome P450 catalysis.
Angewandte Chemie, 2015Cytochromes P450 can catalyze various regioselective and stereospecific oxidation reactions of non-functionalized hydrocarbons. Here, we have designed a novel light-driven platform for cofactor-free, whole-cell P450 photo-biocatalysis using eosin Y (EY ...

Prothrombin as cofactor for antiphospholipids
Lupus, 1998Prothrombin is a common antigenic target of antiphospholipid antibodies, since anti-prothrombin antibodies are detected in about 50-90% of the patients. To allow proper immune recognition, prothrombin must be adsorbed on suitable anionic surfaces. The epitope(s) have not yet been identified: the majority of anti-prothrombin antibodies appear to be of ...

The decarboxylation of antimicrobial aromatic acids such as phenylacrylic acid (cinnamic acid) and ferulic acid by yeast requires two enzymes described as phenylacrylic acid decarboxylase (PAD1) and ferulic acid decarboxylase (FDC).

It is known that many enzymes function only in conjunction with a coenzyme (cofactor) which is generally a compound of low molecular weight. Immobilization of these compounds has been the focus of much effort because of their potential as bioaffinity ligands and in the search for immobilized coenzymes retaining “biological activity”, which are readily ...

Pollen, a non-chlorophyllous tissue, contains enzymes to metabolize external and internal substrates essential for tube growth. In some species tube extension occurs minutes after a grain lands in the proper environment; in others, growth occurs several days or weeks after pollination.

Iron cofactor assembly in plants.
Annual Review of Plant Biology, 2014Iron is an essential element for all photosynthetic organisms. The biological use of this transition metal is as an enzyme cofactor, predominantly in electron transfer and catalysis.

Publisher Summary Tyrosyl radicals are found in enzymes that catalyze a wide spectrum of chemical reactions, and their functional importance is well established in class I ribonucleotide reductase (RNR), prostaglandin H synthase (PGHS), and photosystem II (PSII).

Molybdenum cofactor deficiency
The Journal of Pediatrics, 1993We describe a new case of molybdenum cofactor deficiency, an underrecognized inborn error of metabolism that results in neonatal seizures and neurologic abnormalities. Characteristic biochemical defects in affected individuals include hypouricemia, elevated urine sulfate (detectable by dipstick), and elevated S-sulfocysteine (detectable by anion ...

Enzymes such as oxidoreductases and transferases are able to catalyze industrially useful reactions. However, these enzymes are often cofactor dependent. Cofactors are relatively low molecular weight compounds that are required for the enzymatic reactions.

721 REDOX-ACTIVE COFACTORS, including quinones and flavins, are important components in biological systems. Together with the apoprotein, they perform complex redox chemistry, provide an important link in signal transduction, and participate in crucial electron transfer pathways, aspects that are often inefficiently carried out by the proteins ...
