WebMass spectrometry (MS) has been successfully applied for the identification and quantification of uremic toxins and uremia-associated modified proteins. This review focuses on recent progress in the analysis of uremic toxins by using MS. Uremic toxins include low-molecular-weight compounds (e.g., indoxyl sulfate, p-cresol sulfate, 3-carboxy … WebTryptophanase, also described as L-cysteine desulfhydrase, catabolizes L-tryptophan to generate pyruvate, ammonia, and indole.23 The downstream tryptophan permease promotes the influx of free tryptophan into the cell from the environment. Figure 2 outlines the currently accepted mechanism of tna operon regulation under low (Figure 2A) and high ...
