PAP1 — Nicotiana attenuata

Summary

A4A49_10651 (PAP1) in coyote tobacco (Nicotiana attenuata) encodes a purple acid phosphatase (PAP) family protein with phosphoenolpyruvate phosphatase, acid phosphatase, and protein phosphatase activities, and binds ferric iron, manganese, and zinc. The gene is associated with secondary metabolism, including nicotine and alkaloid anabolism, flavonoid and phenylpropanoid metabolism, anthocyanin anabolism and pigmentation, and detoxification. It has also been linked to leaf development, ABA signaling, cellular response to phosphate starvation, and syngamy. The encoded protein localizes to the vacuolar lumen, plant-type cell wall, and extracellular space. Additionally, this gene is associated with chlorophyll content. Studies of related genes in other species link the family to broad phosphatase activities (EC 3.1.3.60).
