Crystal structure of yeast allantoicase reveals a repeated jelly roll motif.

Allantoicase (EC catalyzes the conversion of allantoate into ureidoglycolate and urea, one of the final steps in the degradation of purines to urea. The mechanism of most enzymes involved in this pathway, which has been known for a long time, is unknown. In this paper we describe the three-dimensional crystal structure of the yeast allantoicase determined at a resolution of 2.6 A by single anomalous diffraction. This constitutes the first structure for an enzyme of this pathway. The structure reveals a repeated jelly roll beta-sheet motif, also present in proteins of unrelated biochemical function. Allantoicase has a hexameric arrangement in the crystal (dimer of trimers). Analysis of the protein sequence against the structural data reveals the presence of two totally conserved surface patches, one on each jelly roll motif. The hexameric packing concentrates these patches into conserved pockets that probably constitute the active site.

FIG. 3. A, representation of the allantoicase dimer in the asymmetric unit. The two subunits are related by a 2-fold axis. The labels of the second subunit are primed. B, ribbon representation of the hexamer generated by P6[3] crystal symmetry. The two subunits of the non-crystallographic dimer are colored in blue and green. The loops containing the regions Ia, IIa, IIIa, and IVa and the regions Ib, IIb, IIIb, and IVb are colored in red and in orange, respectively (same color code as Fig. 2B). The boxed region at the interface is represented in more detail in C. C, detailed representation of the interface between two molecules of the hexamer (B). The interface involves residues from conserved regions I-IV, colored red and orange in modules A and B, respectively (same color code as the other figures). The interface creates a narrow groove lined with conserved residues representing the putative catalytic site.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
