How To Use cytochrome In A Sentence

• Cytochrome P 450 s are a large group of heme - binding enzymes and widely distribute in biology.
• Presently, it is believed that carbon monoxide binds to cytochrome oxidase and consequently, disrupts the mitochondrial respiratory enzyme system. 5,8-11 Experimental studies seem to indicate that delivery of CO dissolved in the serum to the cells, and not blockage of oxygen transport by the COHb bond, is perhaps more important in the sequence of pathological events of the poisoning. 3,14 Although in severe poisonings, all factors may contribute to the outcome of the case. Carbon Monoxide
• EPR-and light absorbance spectroscopy [3]; mouse macrophage enzyme: cytochrome P-450 type hemoprotein [9]; naturally occuring neuronal mutant with a 105-amino acid deletion in the heme-binding domain as a result of in-frame mutation by specific alternative splicing, contains heme, but shows no l-arginine and NADPH-dependent citrulline-forming activity in presence of Ca2+ - promoted calmodulin, the heme coordination geometry is highly abnormal [28]; Recently Uploaded Slideshows
• Iron is used in actively proliferating cells for cytochrome and DNA synthesis.
• Cytochrome oxidases are the terminal enzymes of aerobic electron transport phosphorylation.
• Woese then hazarded that such chimerism probably would not prove a significant problem, from the example provided by congruent alpha-proteobacterial trees based on cytochromes c and rRNA, from the general robustness of the rRNA phylogeny, and from its ability to predict certain domain-level phenotypic characters (for instance, the differences in bacterial and archaeal cell envelopes, transcription, and translation). A Disclaimer for Behe?
• The many hundred known forms of cytochrome P450 are notably involved in detoxification of xenobiotics and steroid biosynthesis, but also in adverse reactions such as activation of procarcinogens.
• Our previous results indicated that cytochrome P450 destruction by benzene metabolites was caused mainly by benzoquinone.
• Our findings suggest that several regions of the cetacean cytochrome b protein have experienced molecular adaptation.
• The active site or prosthetic group of all the cytochromes is an iron containing porphyrin, or heme.
