CC -!- FUNCTION: Catalyzes the interconversion of mannose-6-phosphate to
CC mannose-1-phosphate, the precursor for the synthesis of GDP-mannose.
CC GDP-mannose is an essential sugar nucleotide for the synthesis of D-
CC mannose-containing cell wall polysaccharides (galactomannans and
CC glucomannans), glycolipids, glycoproteins and the antioxidant L-
CC ascorbate. {ECO:0000256|RuleBase:RU361118}.
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:0000256|ARBA:ARBA00000586,
CC ECO:0000256|RuleBase:RU361118};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|PIRSR:PIRSR605002-3};
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:0000256|ARBA:ARBA00004699,
CC ECO:0000256|RuleBase:RU361118}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738,
CC ECO:0000256|RuleBase:RU361118}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496,
CC ECO:0000256|RuleBase:RU361118}.
CC -!- SIMILARITY: Belongs to the eukaryotic PMM family.
