Proteins/UNIPROT:Q9Y5P6
Catalytic subunit of the GMPPA-GMPPB mannose-1-phosphate guanylyltransferase complex. Catalyzes the formation of GDP-mannose, an essential precursor of glycan moieties of glycoproteins and glycolipids. Can catalyze the reverse reaction in vitro. Together with GMPPA regulates GDP-alpha-D-mannose levels..
