CC -!- FUNCTION: Catalyzes the interconversion of mannose-6-phosphate to
CC mannose-1-phosphate, the precursor for the synthesis of GDP-mannose
CC (Probable). 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). Can complement the yeast
CC temperature-sensitive mutant sec53-6 (PubMed:17217471).
CC {ECO:0000269|PubMed:17217471, ECO:0000305,
CC ECO:0000305|PubMed:17217471}.
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:0000305|PubMed:17217471};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:Q92871};
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:0000305}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:Q92871}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:A0A0U1WZ18}.
CC -!- SIMILARITY: Belongs to the eukaryotic PMM family. {ECO:0000305}.
