Term Name:	(2Z,4E)-3-(2-carboxy-1-hydroxyethyl)-2,4-hexadienedioic acid
Synonyms:	(2E,4Z)-4-(carboxymethylene)-5-hydroxyhept-2-enedioic acid
Definition:	A tricarboxylic acid that is hexa-2,4-dienedioic acid which is substituted at position 3 by a 2-carboxy-1-hydroxyethyl group (the 2Z,4E isomer; a mixture of isomers at the carbon bearing the alcoholic hydroxy group). It has been produced from trans-caffeic acid using Aspergillus niger, but the conversion rate was increased 3.5 times by using a coculture of Streptomyces coelicolor and Aspergillus niger.
