Metabolite Identification
Common NameMethoxyflurane
DescriptionMethoxyflurane, also known as metoxiflurano or penthrane, belongs to the class of organic compounds known as dialkyl ethers. These are organic compounds containing the dialkyl ether functional group, with the formula ROR', where R and R' are alkyl groups. An ether in which the two groups attached to the central oxygen atom are methyl and 2,2-dichloro-1,1-difluoroethyl. Methoxyflurane is a drug which is used for use in the induction and maintenance of general anesthesia. Methoxyflurane is an extremely weak basic (essentially neutral) compound (based on its pKa). Methoxyflurane is a potentially toxic compound.

Enzymes

General function:
Involved in oxidation reduction
Specific function:
Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone (By similarity).

General function:
Involved in monooxygenase activity
Specific function:
Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1'-hydroxylation and midazolam 4-hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Acts as a 1,8-cineole 2-exo-monooxygenase. The enzyme also hydroxylates etoposide.

General function:
Involved in hydrogen ion transporting ATP synthase activity, rotational mechanism
Specific function:
Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - containing the extramembraneous catalytic core, and F(0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP turnover in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation. Part of the complex F(1) domain and of the central stalk which is part of the complex rotary element. Rotation of the central stalk against the surrounding alpha(3)beta(3) subunits leads to hydrolysis of ATP in three separate catalytic sites on the beta subunits
