Description : (at3g07130 : 209.0) Encodes PAP15, a purple acid phosphatase with phytase activity. Expression of PAP15 is developmentally and temporally regulated, with strong expression at the early stages of seedling growth and pollen germination. The expression is also organ/tissue-specific, with strongest expression in the vasculature, pollen grains, and roots. Recombinant PAP protein exhibits broad substrate specificity with moderate phytase activity. PAP15 likely mobilizes phosphorus reserves in plants, particularly during seed and pollen germination.; purple acid phosphatase 15 (PAP15); FUNCTIONS IN: protein serine/threonine phosphatase activity, acid phosphatase activity; INVOLVED IN: pollen germination, seed germination; LOCATED IN: endomembrane system; EXPRESSED IN: 11 plant structures; EXPRESSED DURING: seedling growth, petal differentiation and expansion stage; CONTAINS InterPro DOMAIN/s: Purple acid phosphatase, N-terminal (InterPro:IPR015914), Metallophosphoesterase (InterPro:IPR004843), Purple acid phosphatase-like, N-terminal (InterPro:IPR008963); BEST Arabidopsis thaliana protein match is: purple acid phosphatase 13 (TAIR:AT2G32770.3); Has 2322 Blast hits to 2305 proteins in 472 species: Archae - 7; Bacteria - 914; Metazoa - 228; Fungi - 75; Plants - 768; Viruses - 0; Other Eukaryotes - 330 (source: NCBI BLink). & (reliability: 418.0) & (original description: no original description)
