Indolepyruvate
The thiamin diphosphate (ThDP)-dependent enzyme indolepyruvate decarboxylase (IPDC) is involved in the biosynthetic pathway of the phytohormone 3-indoleacetic acid and catalyzes the nonoxidative decarboxylation of 3-indolepyruvate to 3-indoleacetaldehyde and carbon dioxide. (PMID:15835904)  In addition, the enzyme was compared with the phenylpyruvate decarboxylase from Azospirillum brasilense and the indolepyruvate decarboxylase from Enterobacter cloacae. (PMID:21501384) Indole-3-pyruvate is a microbial metabolite, urinary indole-3-pyruvate is produced by Clostridium sporogenes (PMID:29168502) and Trypanasoma brucei (PMID:27856732). Indolepyruvate, also known as indolepyruvic acid or (indol-3-yl)pyruvate, belongs to indolyl carboxylic acids and derivatives class of compounds. Those are compounds containing a carboxylic acid chain (of at least 2 carbon atoms) linked to an indole ring. Indolepyruvate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Indolepyruvate can be found in a number of food items such as spelt, strawberry, gram bean, and oregon yampah, which makes indolepyruvate a potential biomarker for the consumption of these food products. Indolepyruvate exists in all eukaryotes, ranging from yeast to humans.
