TphA3 is coding for the small terephthalate 1,2-dioxygenase subunit from Comamonas testosteroni KF-1. TphA3 forms together with TphA1 and TphA2 the terephthalic acid 1,2-dioxygenase system (TERDOS). TERDOS catalyzes the first reaction in the terephthalic acid degradation



Usage and Biology

The monomer of TphA3 consists of 155 amino acids and has a molar mass of 17.36 kDa. Gel permeation chromatography shows that TphA3 has a homotrimeric structure and a mass of 52.08 kDa.
