Mediates the NAD(+) import into chloroplast. Favors the NAD(+)(in)/ADP or AMP(out) antiport exchange, but is also able to catalyze a low unidirectional transport (uniport) of NAD(+). Transports NAD(+), nicotinic acid adenine dinucleotide, nicotinamide mononucleotide, nicotinic acid mononucleotide, FAD, FMN, TTP, TDP, TMP, UTP, UDP, UMP, CTP, CDP, CMP, GTP, GDP, GMP, 3'-AMP, ATP, ADP, AND AMP, has low transport activity with cAMP, pyrophosphate, NADH and alpha-NAD(+), and has no activity with NADP(+), NADPH, nicotinamide, nicotinic acid, adenosine, thiamine mono- or diphosphate, inorganic phosphate, CoA, folate, NaCl, malate, malonate, citrate, fumarate, aspartate, glutamate, S-adenosylmethionine, lysine, arginine, and ornithine.
