Structure of the catalytic chain of Methanococcus jannaschii aspartate transcarbamoylase in a hexagonal crystal form: insights into the path of carbamoyl phosphate to the active site of the enzyme

The structure of the catalytic chain of Methanococcus jannaschii aspartate transcarbamoylase has been determined in a hexagonal crystal form and gives insight into the possible paths that the substrate carbamoyl phosphate may follow to reach the active site during catalysis.
