FractionRelative Enzyme Concentration
GA20 6.46.924.5
GA29 66.679.574.0

Lysate of bacteria expressing GA 2-oxidase was diluted with inactive control lysate and incubated overnight at 20°C with substrate and cofactors. Products were separated by HPLC. Results are expressed as percentages of total counts in substrate and product fractions.
