Abstract

Our understanding of nicotinamide adenine dinucleotide mitochondrial transporter 1 (Ndt1A) in Aspergillus fumigatus remains poor. Thus, we investigated whether Ndt1A could alter fungi survival. To this end, we engineered the expression of an Ndt1A-encoding region in a Delta ndt1 Delta ndt2 yeast strain. The resulting cloned Ndt1A protein promoted the mitochondrial uptake of nicotinamide adenine dinucleotide (NAD(+)), generating a large mitochondrial membrane potential. The NAD(+) carrier utilized the electrochemical proton gradient to drive NAD(+) entrance into mitochondria when the mitochondrial membrane potential was sustained by succinate. Its uptake has no impact on oxidative stress, and Ndt1A expression improved growth and survival of the Delta ndt1 Delta ndt2 Saccharomyces cerevisiae strain. (AU)
