Protein Name: Inositol-phosphate phosphatase

UniprotKB/SwissProt ID: Q9M8S8 (Q9M8S8)

Gene Name: VTC4

Organism: Arabidopsis thaliana (Mouse-ear cress)

Function: Phosphatase acting on L-galactose 1-phosphate (L-Gal 1-P), D-myoinositol 3-phosphate (D-Ins 3-P) and D-myoinositol 1-phosphate (D-Ins 1-P). Can also use beta-glycerophosphate (glycerol 2-P) and, to a lesser extent, D-galactose 1-phosphate (D-Gal 1-P), alpha-D-glucose 1-phosphate (a-D-Glc 1-P), D-mannitol 1-phosphate and adenosine 2'-monophosphate as substrates. No activity with D-fructose 1-phosphate (D-Fru 1-P), fructose 1,6-bisphosphate (Fru 1,6-bisP), D-glucose 6-phosphate (D-Glc 6-P), D-alpha-glycerophosphate (glycerol 3-P), D-sorbitol 6-phosphate and D-myoinositol 2-phosphate. The C1 phosphate position in a six-member ring substrate is important for catalysis
