One enzyme which catalyzes the last step of the formation of the hormone retinoic acid from vitamin A (retinol) is retinal dehydrogenase type II (RalDH2). RalDH2, expressed in the Escherichia coli BL21(DE3) strain, was purified and crystallized using ammonium sulfate as a precipitant. These crystals belong to the space group P 2 1 2 1 2 1 ( a = 108, b = 150, c = 168 Å, α = β = γ = 90°).
