Nitration of Tyr164 and Tyr208 would destabilize the closed state of loop 6 because the interaction between Tyr208 and Ala176 through an H-bond would be compromised (Fig. 2A and B; Supplementary Fig. S2). Indeed, purified TPI after nitrotyrosination with a peroxynitrite donor (SIN-1) displayed a significant decrease in isomerase activity in both directions of the catalysis, i.e. using DHAP (Fig. 2C) or GAP (Fig. 2D) as substrate.
