1
CI was purified to electrophoretic homogeneity from cell-free extracts of Proteus sp.
2
The enzyme was purified about 9-fold to electrophoretic homogeneity and is localised in the soluble fraction.
3
The enzyme was purified 20-fold by a 5 step procedure to electrophoretic homogeneity.
4
The recombinant enzyme was purified in mg amounts from the bacterial lysate to electrophoretic homogeneity and characterized with respect to its protein-chemical and enzymatic properties.
