Aryl hydrocarbon (benzo[a]pyrene) hydroxylase: a mixed-function oxygenase in mouse skin. 1975

F J Wiebel, and J C Leutz, and H V Gelboin

Mouse skin contains aryl hydrocarbon (benzo[a]pyrene) hydroxylase activity which is inducible by aromatic polycyclic hydrocarbons and benzoflavones. The duration and magnitude of induction, but not the initial kinetics, are dependent on the inducer dose. The cutaneous hydroxylase activity is inhibited by carbon monoxide and requires the presence of NADPH, indicating that the enzyme is one of the mixed-function oxygenases. The highest enzyme activity was found in the superficial layer of skin which contains the sebaceous glands and the upper pilary canals. Enzyme activities were intermediate in the epidermis and lowest in the deeper dermal layers.

D009249	NADP	Nicotinamide adenine dinucleotide phosphate. A coenzyme composed of ribosylnicotinamide 5'-phosphate (NMN) coupled by pyrophosphate linkage to the 5'-phosphate adenosine 2',5'-bisphosphate. It serves as an electron carrier in a number of reactions, being alternately oxidized (NADP+) and reduced (NADPH).

D002248	Carbon Monoxide	Carbon monoxide (CO). A poisonous colorless, odorless, tasteless gas. It combines with hemoglobin to form carboxyhemoglobin, which has no oxygen carrying capacity. The resultant oxygen deprivation causes headache, dizziness, decreased pulse and respiratory rates, unconsciousness, and death. (From Merck Index, 11th ed)	Monoxide, Carbon
D004790	Enzyme Induction	An increase in the rate of synthesis of an enzyme due to the presence of an inducer which acts to derepress the gene responsible for enzyme synthesis.	Induction, Enzyme
