2.3.1.221
Noranthrone synthase.
based on mapping to UniProt Q12053
7 malonyl-CoA + hexanoyl-[acyl-carrier protein] = 7 CoA + norsolorinate anthrone + [acyl-carrier protein] + 7 CO(2) + 2 H(2)O.
-!- A multi-domain polyketide synthase involved in the synthesis of aflatoxins in the fungus Aspergillus parasiticus. -!- The hexanoyl starter unit is provided to the acyl-carrier protein (ACP) domain by a dedicated fungal fatty acid synthase.
