Description2-Aminobenzoic acid, also known as vitamin L1 or anthranilic acid, belongs to the class of organic compounds known as aminobenzoic acids. These are benzoic acids containing an amine group attached to the benzene moiety. 2-Aminobenzoic acid is a moderately basic compound (based on its pKa). 2-Aminobenzoic acid exists in all living species, ranging from bacteria to humans. Within yeast, 2-aminobenzoic acid participates in a number of enzymatic reactions. In particular, pyruvic acid, L-glutamic acid, and 2-aminobenzoic acid can be biosynthesized from chorismate and L-glutamine; which is mediated by the enzyme anthranilate synthase component. In addition, 2-aminobenzoic acid and phosphoribosyl pyrophosphate can be converted into N-(5-phosphoribosyl)-anthranilate; which is catalyzed by the enzyme anthranilate phosphoribosyltransferase. In yeast, 2-aminobenzoic acid is involved in the metabolic pathway called the tryptophan metabolism pathway. 2-Aminobenzoic acid is a potentially toxic compound.
