PAP1 — Nicotiana attenuata

Summary

A4A49_17344 (PAP1, also known as PAP18) 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, alkaloid, anthocyanin, flavonoid, and phenylpropanoid anabolism, as well as pigmentation, detoxification, leaf development, ABA signaling, and the cellular response to phosphate starvation. It is also linked to chlorophyll content. The encoded protein localizes to the vacuolar lumen, plant-type cell wall, and extracellular space. Related genes in other species connect the family to additional phosphatase activities (EC 3.1.3.60).
