- General Function
- Hydrolyzes both GDP-mannose and GDP-glucose (PubMed:10913267, PubMed:23481913, PubMed:7592609). Could participate in the regulation of cell wall biosynthesis by influencing the concentration of GDP-mannose or GDP-glucose in the cell. Might also be involved in the biosynthesis of the slime polysaccharide colanic acid (PubMed:10913267, PubMed:7592609).
