Abstract

The enzyme 1-aminocyclopropane-1-carboxylic acid deaminase from the bacterium Pseudomonas sp. has been crystallized using the hanging-drop method. The crystals belong to the orthorhombic space group P 212121 (a = 70.0 Å, b = 70.0 Å, c = 355.0 Å). An asymmetrical unit contains two trimer molecules of Mr = 110,000. The diffraction data have been collected to 3.5-Å resolution. Analysis of the data using the self-rotation function suggests threefold axes within the trimer molecules and a pseudotetragonal arrangement between the trimer molecules in the cell.
