Functionally analogous are the Peroxiredoxins (Prx) , which use the same mechanism but with a cysteine active site that shuttles from the thiolate (S-H) to the sulphinic acid (S-OH) form and is reduced back by glutathione
Finally, a glutamine-enriched diet is also shown to increase the abundance of beneficial Bifidobacteria in the jejunum of healthy weaned mice (194), and to decrease potentially harmful microorganisms in adult pigs (196)
In beagle dogs, the absolute bioavailability reaches approximately 4%, with Cmax values of 0.421.44 g/mL following oral doses of 1040 mg/kg and corresponding AUC values of 47.28183.14 mg.min/L
although its chemical activity is similar to the original drug, MTX-PG 2-6 is preferentially kept in the intracellular environment [whereas non-glutamylated MTX is quickly exported by ABC transporters ( MTX primarily acts by inhibiting dihydrofolate reductase (DHFR), which catalyzes the sequential conversion of folic acid to dihydrofolate (DHF) and tetrahydrofolate (THF)
