transferase complex, transferring phosphorus-containing groups GDP-mannose pyrophosphorylase complex https://github.com/geneontology/go-ontology/issues/27827 GO:0120508 GMPPA-GMPPB complex cellular_component A protein complex capable of catalyzing the reaction of GTP and mannose-1-phosphate to form GDP-mannose. The complex is a homodimer in most bacteria and a heterodimer in most eukaryotes. In humans, it is composed of a catalytic beta subunit (GMPPB) and a regulatory alpha subunit (GMPPA). sjm 2024-05-04T08:30:37Z
