GDP-mannose pyrophosphorylase complex
gdp-mannose pyrophosphorylase complex
"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)."
