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


Usage and Biology

TphA2 consists of 414 amino acids and has a molar mass of 46.35 kDa. It is a Rieske protein with a iron-sulfuric center. The Rieske center is located in the active site and is typical for oxygenases. Figure 1 shows TphA1 with the Rieske center.
