Protein
Alkyl hydroperoxide reductase AhpD
Organism
Mycobacterium tuberculosis (strain CDC 1551 / Oshkosh)
Function
Together with AhpC, DlaT and Lpd, constitutes an NADH-dependent peroxidase active against hydrogen and alkyl peroxides as well as serving as a peroxynitrite reductase, thus protecting the bacterium against reactive nitrogen intermediates and oxidative stress generated by the host immune system.
Similarity
Belongs to the AhpD family.
