, condensing a molecule of benzoyl-CoA with three
malonyl-CoA
Malonyl-CoA is a coenzyme A derivative of malonic acid.
Functions
It plays a key role in chain elongation in fatty acid biosynthesis and polyketide biosynthesis.
Fatty acid biosynthesis
Malonyl-CoA provides 2-carbon units to fatty acids and commi ...
, yielding to
2,4,6-trihydroxybenzophenone. This intermediate is subsequently converted by a
benzophenone 3′-hydroxylase
Benzophenone is the organic compound with the formula (C6H5)2CO, generally abbreviated Ph2CO. It is a white solid that is soluble in organic solvents. Benzophenone is a widely used building block in organic chemistry, being the parent diarylket ...
, a cytochrome P450 monooxygenase, leading to the formation of
2,3′,4,6-tetrahydroxybenzophenone.
Benzoyl-CoA is a substrate of benzoyl-CoA reductase. This enzyme is responsible in part for the reductive
dearomatization of aryl compounds mediated by bacteria under anaerobic conditions.
