Nitroindazole acts as a selective inhibitor for neuronal nitric oxide synthase, a hemoprotein enzyme that, in neuronal tissue, converts arginine to citrulline and nitric oxide ( NO ).
12.
"' Cytochromes " b " 5 "'are ubiquitous electron transport hemoproteins found in animals, plants, fungi and animal tissues are water-soluble.
13.
It has been speculated that the original evolutionary function of hemoproteins was electron transfer in primitive sulfur-based photosynthesis pathways in ancestral cyanobacteria-like organisms before the appearance of molecular oxygen.
14.
NOSs are hemoproteins that combine reductase and oxygenase catalytic domains in one monomer to synthesize NO from the terminal nitrogen atom of L-arginine in the presence of NADPH and O 2.
15.
Lignin peroxidase ( also " ligninase ", EC number 1.14.99 ) is a hemoprotein firstly isolated from the white-rot fungus " Phanerochaete chrysosporium " with a variety of lignin-degrading reactions, all utilizing hydrogen peroxide as an oxygen source.
16.
NOSs can be dimeric, calmodulin-dependent or calmodulin-containing cytochrome p450-like hemoprotein that combines reductase and oxygenase catalytic domains in one dimer, bear both flavin adenine dinucleotide ( FAD ) and flavin mononucleotide ( FMN ), and carry out a 5 `-electron oxidation of non-aromatic amino acid arginine with the aid of tetrahydrobiopterin.
17.
"' Cytochrome P450 reductase "'(; also known as NADPH : ferrihemoprotein oxidoreductase, NADPH : hemoprotein oxidoreductase, NADPH : P450 oxidoreductase, P450 reductase, "'POR "', CPR, CYPOR ) is a membrane-bound enzyme required for electron transfer from NADPH to cytochrome P450 in the endoplasmic reticulum of the cell.
18.
The family of cytochrome " b " 5-like proteins includes ( besides cytochrome " b " 5 itself ) hemoprotein domains covalently associated with other redox domains in flavocytochrome cytochrome " b " 2 ( L-lactate dehydrogenase; ), sulfite oxidase ( ), plant and fungal nitrate reductases (,, ), and plant and fungal cytochrome " b " 5 / acyl lipid desaturase fusion proteins.
