Protein Phosphatase Classification:      PPP/SLP

※ SLP family introduction

    SLP is a unique family of PPP group which is highly conserved among all plants and members also can be found in fungi and bacterias. Arabidopsis thaliana contains two SLP phosphatases: SLP1 and SLP2. SLP1 and SLP2 exist in different cellular compartments. For example, SLP1 is found in chloroplastic and SLP2 is found in cytosolic. SLP is a type of metal cation dependent phosphatase and shows preference to Mn2+ and Fe3+. In addition, SLP members contain core signature motifs of PPP group phosphatases and act as Ser/Thr protein phosphatases (1).
