PAP1 — Nicotiana attenuata

Summary

A4A49_07750 (PAP1) in coyote tobacco (Nicotiana attenuata) encodes a purple acid phosphatase (PAP) family protein with phosphoenolpyruvate phosphatase, acid phosphatase, and protein phosphatase activities, binding ferric iron, manganese, and zinc. It is associated with flavonoid metabolism, regulation of anthocyanin anabolism, phenylpropanoid metabolism, alkaloid anabolism, detoxification, secondary metabolism, anthocyanin anabolism, phenylpropanoid anabolism, cellular response to phosphate starvation, leaf development, and ABA signaling. The gene is linked to chlorophyll content. The product localizes to the vacuolar lumen, plant-type cell wall, and extracellular space. Studies of related genes in other species connect the family to additional phosphatase activities (EC 3.1.3.60).
