CC -!- FUNCTION: Catalyzes the interconversion of mannose-6-phosphate to
CC mannose-1-phosphate, the precursor for the synthesis of GDP-mannose
CC (PubMed:9003801). GDP-mannose is an essential sugar nucleotide for the
CC synthesis of D-mannose-containing cell wall polysaccharides
CC (galactomannans and glucomannans), glycolipids, glycoproteins and the
CC antioxidant L-ascorbate (Probable). {ECO:0000269|PubMed:9003801,
CC ECO:0000305}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=alpha-D-mannose 1-phosphate = D-mannose 6-phosphate;
CC Xref=Rhea:RHEA:11140, ChEBI:CHEBI:58409, ChEBI:CHEBI:58735;
CC EC=5.4.2.8; Evidence={ECO:0000269|PubMed:9003801};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:Q92871};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=3 uM for glucose-1-phosphate {ECO:0000269|PubMed:23471408};
CC KM=4 uM for mannose-1-phosphate {ECO:0000269|PubMed:23471408};
CC Note=Glucose-1,6-bisphosphate or mannose-1,6-biphosphate are
CC essential for activity. {ECO:0000269|PubMed:9003801};
CC -!- PATHWAY: Nucleotide-sugar biosynthesis; GDP-alpha-D-mannose
CC biosynthesis; alpha-D-mannose 1-phosphate from D-fructose 6-phosphate:
CC step 2/2. {ECO:0000269|PubMed:9003801, ECO:0000305}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:Q92871}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:A0A0U1WZ18}.
CC -!- SIMILARITY: Belongs to the eukaryotic PMM family.
CC {ECO:0000269|PubMed:9003801}.
