1.96 angstrom x-ray crystal structure of 3-hydroxyanthranilate-3,4-dioxygenase bound with 3-aminosalicylic acid from cupraavidus metallidurans

Function

[3HAO_RALME] Catalyzes the oxidative ring opening of 3-hydroxyanthranilate to 2-amino-3-carboxymuconate semialdehyde, which spontaneously cyclizes to quinolinate.^[1]
