A study is presented on the crystallization of ornithine acetyltransferase from yeast, which catalyzes the fifth step in microbial arginine synthesis. The use of the counter‐diffusion technique removes the disorder present in one dimension in crystals grown by either the batch or hanging‐drop techniques. This makes the difference between useless crystals and crystals that allow successful determination of the structure of the protein. The crystals belong to space group P 4, with unit‐cell parameters a = b = 66.98, c = 427.09 Å, and a data set was collected to 2.76 Å.
