The enzyme aminocarboxymuconate-semialdehyde decarboxylase (EC 4.1.1.45) catalyzes the chemical reaction:
The product spontaneously ring-closes to picolinic acid, with loss of water.
This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. This enzyme is part of the kynurenine pathway in tryptophan metabolism, leading to picolinic acid or quinolinic acid. It has been identified as a marker in nonverbal autism.
