Function

[QDOI_ASPJA] Performs the first step in the degradation of the flavonoid quercetin by a dioxygenase reaction. The enzyme catalyzes the cleavage of the O-heteroaromatic ring of the flavonol quercetin yielding the depside 2-protocatechuoyl-phloroglucinol carboxylic acid and carbon monoxide. This involves the remarkable dioxygenolytic cleavage of two carbon-carbon bonds.

About this Structure

1h1i is a 4 chain structure with sequence from Aspergillus japonicus. Full crystallographic information is available from OCA.
