AI Article Synopsis
- * Different isoforms of PAPs are found in various parts of the plant Setaria italica, and their expression increases when the plant is low on phosphorus, helping to improve phosphorus availability.
- * Researchers isolated the SiPAP18 gene and created a protein model based on a similar structure from kidney beans, highlighting five important conserved features and seven metal-binding amino acids that are crucial for phosphorus enhancement under nutrient-poor conditions.
Article Abstract
Purple acid phosphatases belong to metallo-phosphatase family. Intracellular phosphatases are crucial for phosphorus (P) distribution in the cell and are highly induced in phosphorus-deprived conditions in the soil. Disparate PAP isoforms exist within discrete subcellular compartments in Setaria italica and their expression in P deprived conditions fosters phosphorus amelioration. We isolated the SiPAP18 gene and developed the homology SiPAP18 protein model based on the crystal structure of the Kidney bean PvPAP (PDB ID: 2QFP) as template (sequence similarity 42.7%) using Modeller 9.12 with adequate validation. Structure model analysis shows the significance of five conserved signatures with seven metal-paired amino acid residues during P-deprivation induced phosphorus amelioration.
