MPO is the most abundant hemoprotein
in leukocytes and comprises approximately 5% of their dry weight (Klebanoff 2005).
Tissue hypoxia resulting from a large COHb load, in clinical terms, has the greatest influence on the heart, and CO binding to hemoproteins
, including cytochrome, myoglobin and guanylate cyclase, contributes to the clinical syndrome (9,10).
This information underlines the significance of hemoproteins in NO generation enzymatically.
Formation of nitrogen oxides and citrulline upon oxidation of Nw-hydroxy-l-arginine by hemoproteins.
P450 enzymes are a superfamily of hemoproteins
, which catalyze the Phase I biotransformation of various substrates, oxidizing these compounds into forms which are easily eliminated by the body.
2] binding curves of hemoproteins
by means of a diffusion chamber.
The mechanism by which this inhibition takes place is thought to be related to chelation of free iron which is released from hemoproteins
of meat during heat processing.
The steady-state level of hepatic heme is the net result of biosynthesis, degradation, and incorporation of heme into hemoproteins
within the liver.
The colour of raw meat comes from its hemoproteins
, principally myoglobin.
Plant peroxidases, like Hb, are hemoproteins
that have the prosthetic group ferriprotoporphyrin IX (hemin) (5).
