WebIDO and tryptophan metabolism In order to confirm that the measurement of IDO by flow cytometry has functional relevance, we assessed tryptophan metabolism by UPLC-MS/MS. A higher MFI for IDO in PBMCs was correlated with a higher Kyn/Tryp ratio (p D 0.008, CC 0.389) and with lower tryptophan levels (p D 0.014, CC ¡0.364). WebJan 21, 2010 · It showed maximum activity at 30 to 60°C (Fig. 1a), and at pH 7 (Fig. 1b). Open in a separate window. Figure 1. Effect of temperature and pH on drDDC activity. ... to all the tested substrates. Although the tryptophan residue in the mutant should interact with the PLP pyridine ring in a manner similar to histidine residue of the ...
