HHsearch alignment for GI: 254780968 and conserved domain: cd03026

>cd03026 AhpF_NTD_C TRX-GRX-like family, Alkyl hydroperoxide reductase F subunit (AhpF) N-terminal domain (NTD) subfamily, C-terminal TRX-fold subdomain; AhpF is a homodimeric flavoenzyme which catalyzes the NADH-dependent reduction of the peroxiredoxin AhpC, which then reduces hydrogen peroxide and organic hydroperoxides. AhpF contains an NTD containing two contiguous TRX-fold subdomains similar to Pyrococcus furiosus protein disulfide oxidoreductase (PfPDO). It also contains a catalytic core similar to TRX reductase containing FAD and NADH binding domains with an active site disulfide. The proposed mechanism of action of AhpF is similar to a TRX/TRX reductase system. The flow of reducing equivalents goes from NADH - catalytic core of AhpF - NTD of AhpF - AhpC - peroxide substrates. The catalytic CXXC motif of the NTD of AhpF is contained in its C-terminal TRX subdomain.
