Crystallization (Commentary)

Crystallization (Comment) Organism
of wild-type and mutants Y104A, Y104F Escherichia coli

Protein Variants

Protein Variants Comment Organism
Y104A 0.1% of wild-type activity. Crystallization data. The M2+ metal-binding site is absent in the structure, but Mg2+ is still present and bound to C67, E87, and four water molecules Escherichia coli
Y104F 0.1% of wild-type activity. Crystallization data. General fold of enzyme is similar to wild-type Escherichia coli
