AtzF forms a large, ca. 660-kDa, multienzyme complex with cyanuric acid amidohydrolase AtzD and biuret amidohydrolase AtzE. Analysis of the multimerization of AtzF and Atzf467 by small-angle x-ray scattering (SAXS) 752542 3.5.1.54 additional information urea amidolyase is composed of urea carboxylase (UC) and allophanate hydrolase (AH) domains. KlUC and KlAH are monomeric and dimeric in solution, respectively. The relatively smaller UC-AH interface therefore does not play a major role in the UA holo-enzyme assembly. In the isolated KlAH, the active sites are located near the dimer interface. The extensive interactions at the dimer interface most likely stabilize the structure of the active sites. Consistent with this, the G559E/G572E mutation that renders the isolated KlAH monomeric severely inhibited its activity -, 744532 3.5.1.54 tetramer 4 * 66223, sequence calculation 669098
