Peroxiredoxin AhpC gets its reducing equivalents through a cascade of proteins via AhpD, a disulfide reductase, DlaT, a lipoylated disulfide reductase, and, finally, from lpdC, the NADH-dependent dihydrolipoyl reductase. The latter two are also part of the pyruvate dehydrogenase complex (Venugopal et al. 2011).
