Comment typeDescription
Biophysicochemical PropertiesKinetic parameters: Vmax=13.1 umol/min/mg enzyme toward glycerolphosphoglycerol {ECO:0000269|PubMed:21323773}; Vmax=12.4 umol/min/mg enzyme toward glycerophosphocholine {ECO:0000269|PubMed:21323773}; Vmax=10.1 umol/min/mg enzyme toward glycerophosphoethanolamine {ECO:0000269|PubMed:21323773};
Catalytic ActivityA glycerophosphodiester + H(2)O = an alcohol + sn-glycerol 3-phosphate. {ECO:0000269|PubMed:21323773}.
CofactorName=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000269|PubMed:21323773};
Disruption PhenotypeNo visible phenotype under normal growth conditions, but mutant plants show reduced glycerophosphodiester phosphodiesterase activity under phosphate starvation. {ECO:0000269|PubMed:21323773}.
FunctionHydrolyzes glycerolphosphoglycerol, glycerophosphocholine and glycerophosphoethanolamine in vitro. May be involved in release of inorganic phosphate (Pi) from phospholipids during Pi starvation. {ECO:0000269|PubMed:21323773}.
InductionBy senescence (PubMed:8883383) and phosphate starvation (PubMed:21323773). {ECO:0000269|PubMed:21323773, ECO:0000269|PubMed:8883383}.
SimilarityBelongs to the glycerophosphoryl diester phosphodiesterase family. {ECO:0000305}.
SimilarityContains 1 GP-PDE domain. {ECO:0000255}.
Subcellular LocationPlastid, chloroplast {ECO:0000269|PubMed:21323773}.
Tissue SpecificityExpressed in roots, shoots, rosette leaves, stems, flowers and siliques. {ECO:0000269|PubMed:21323773}.
