PAP1 — Nicotiana attenuata

Summary

A4A49_40248, designated PAP1/PAP26 in coyote tobacco (Nicotiana attenuata, scaffold02637), encodes a purple acid phosphatase (PAP) family protein with phosphoenolpyruvate phosphatase, acid phosphatase, and protein phosphatase activities, and binds ferric iron, manganese, and zinc. It is associated with secondary metabolism, including nicotine and alkaloid anabolism, flavonoid and phenylpropanoid metabolism, anthocyanin anabolism and pigmentation, and detoxification. The gene is linked to cellular response to phosphate starvation, ABA signaling, leaf development, and syngamy. The product localises to the vacuolar lumen, plant-type cell wall, and extracellular space. Studies of related genes in other species link the family to additional phosphatase activities (EC 3.1.3.60).
