Crystallization (Commentary)

Crystallization (Comment) Organism
crystal structure at 2.0 A. The enzyme shows striking similarity to the structure of the ATP pyrophosphatase domain of GMP synthetase, indicating that both enzyme families have evolved from a common ancestral nucleotide-binding fold Escherichia coli
