GDP-alpha-D-mannose + 2 NAD(+) + H2O = GDP-alpha-D-mannuronate + 2 NADH + 3 H(+)
gdp-alpha-d-mannose + 2 nad(+) + h2o = gdp-alpha-d-mannuronate + 2 nadh + 3 h(+)
GDP-alpha-D-mannose + 2 NAD(+) + H2O = GDP-alpha-D-mannuronate + 2 NADH + 3 H(+)
gdp-alpha-d-mannose + 2 nad(+) + h2o = gdp-alpha-d-mannuronate + 2 nadh + 3 h(+)
