Ab induced nitro-oxidative stress on human neuroblastoma cells, resulting in nitrotyrosination of TPI. Moreover, higher levels of nitro-TPI were also detected in extracts from hippocampus (Fig. 1F) and frontal cortex (Fig. 1G) obtained from Alzheimer’s disease brains, compared with healthy subjects.

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.
