(LOW PHOSPHATE ROOT 1), a bacterial-type plant ferroxidase, is crucial for local root phosphate (Pi) sensing. Here, we present a detailed protocol for native (tag-free) protein purification of LPR1 from leaf extracts by differential ammonium sulfate precipitation, size exclusion, and cation exchange chromatography of a transgenic Arabidopsis thaliana line overexpressing LPR1. We outline steps for LPR1 purification tracking via immune blot analysis and ferroxidase activity assay. The protocol yields highly pure and active LPR1 protein for biochemical analysis. For complete details on the use and execution of this protocol, please refer to Naumann et al. (2022)
