Tryptophan dioxygenase (TDO) and indoleamine 2,3-dioxygenase (IDO) are the only two heme proteins that catalyze the oxidation reaction of tryptophan (Trp) to Nformylkynurenine.While human IDO is able to oxidize both Land D-Trp, human TDO (hTDO) displays major specificity for L-Trp. In this work, we aim to interrogate the molecular basis for the substrate stereoselectivity of hTDO. Our previous molecular dynamics simulation studies of Xanthomonas campestris TDO (xcTDO) showed that a hydrogen bond between T254 (T342 in hTDO) and the ammonium group of the substrate is present in the L-Trp-bound enzyme, but not in the D-Trp-bound enzyme. The fact that this is the only notable structural alteration induced by the change in the stereo structure o...
