CC -!- FUNCTION: Hydrolyzes glucose-6-phosphate to glucose in the endoplasmic
CC reticulum. Forms with the glucose-6-phosphate transporter
CC (SLC37A4/G6PT) the complex responsible for glucose production in the
CC terminal step of glycogenolysis and gluconeogenesis. Hence, it is the
CC key enzyme in homeostatic regulation of blood glucose levels.
CC {ECO:0000250|UniProtKB:P35575}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glucose 6-phosphate + H2O = D-glucose + phosphate;
CC Xref=Rhea:RHEA:16689, ChEBI:CHEBI:4167, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:61548; EC=3.1.3.9;
CC Evidence={ECO:0000250|UniProtKB:P35575};
CC -!- PATHWAY: Carbohydrate biosynthesis; gluconeogenesis.
CC {ECO:0000250|UniProtKB:P35575}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:P35575}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the glucose-6-phosphatase family. {ECO:0000305}.
