tphB: reaction from DCD to protocatechuate

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

TphB is coding for the decarboxylating cis-dihydrodiol dehydrogenase from Comamonas testosteroni Kf-1. It catalyzes the second reaction in the terephthalic acid degration - the decarboxylation of DCD to protocatechuate. The [http://2012.igem.org/Team:TU_Darmstadt/Modeling_Homologie_Modeling#TphB homology modeling] suggests a homodimerization as described by the recent paper by Bains et al.
