PAP1 — Nicotiana attenuata

Summary

A4A49_20395 (PAP1/PAP2) on chromosome 12 of coyote tobacco (Nicotiana attenuata) encodes a purple acid phosphatase (PAP) with phosphoenolpyruvate phosphatase, acid phosphatase, and protein phosphatase activities, and binds ferric iron, manganese, cobalt, and zinc. The gene is associated with anthocyanin and flavonoid metabolism, pigmentation, phenylpropanoid and alkaloid anabolism, nicotine anabolism, secondary metabolism, detoxification, phloem transport, and regulation of carbohydrate metabolism. It is linked to leaf vein morphology, photosynthetic rate, chlorophyll content, phosphate utilization and starvation response, anthocyanin biosynthesis, flavonoid content, leaf senescence, pollen development, abiotic stress tolerance, lipid metabolism, mitochondrial RNA editing, and vascular development. The protein localizes to the vacuolar lumen, mitochondrial envelope, chloroplast outer membrane, endosome, Golgi, and plant-type cell wall.
