tphA1: reduces the tphA2A3 complex

Figure 1. Homology modelling of TphA1. For simulation parameters http://2012.igem.org/Team:TU_Darmstadt/Modeling_Homologie_Modeling#TphA1 click here.

TphA1 is coding for the terephthalate dioxygenase reductase from Comamonas testosteroni KF-1. TphA1 forms together with tphA2 and tphA3 the terephthalic acid 1,2-dioxigenase system (TERDOS). TERDOS catalyzes the first reaction in the terephthalic acid degradation.

Usage and Biology

TphA1 is just like TphA2 an rieske protein. In addition to the rieske center, TphA1 has a binding site for NADPH + H +. The catalytic domäne oxidizes NADPH+H+ and reduces TphA1. Now the reduced TpHA1 reduces the TpHA2A3 complex.
