Crystal structure of Thermotoga maritima alpha-L-fucosidase. Insights into the catalytic mechanism and the molecular basis for fucosidosis.

Fucosylated glycoconjugates are involved in numerous biological events, and alpha-l-fucosidases, the enzymes responsible for their processing, are therefore of crucial importance. Deficiency in alpha-l-fucosidase activity is associated with fucosidosis, a lysosomal storage disorder characterized by rapid neurodegeneration, resulting in severe mental and motor deterioration. To gain insight into alpha-l-fucosidase function at the molecular level, we have determined the crystal structure of Thermotoga maritima alpha-l-fucosidase. This enzyme assembles as a hexamer and displays a two-domain fold, composed of a catalytic (beta/alpha)(8)-like domain and a C-terminal beta-sandwich domain. The structures of an enzyme-product complex and of a covalent glycosyl-enzyme intermediate, coupled with kinetic and mutagenesis studies, allowed us to identify the catalytic nucleophile, Asp(244), and the Brønsted acid/base, Glu(266). Because T. maritima alpha-l-fucosidase occupies a unique evolutionary position, being far more closely related to the mammalian enzymes than to any other prokaryotic homolog, a structural model of the human enzyme was built to document the structural consequences of the genetic mutations associated with fucosidosis.
  Selected figure(s)  
Figure 1.
FIG. 1. The catalytic pocket of TM aFuc. Shown are stereo pairs of the 2F[o] - 2F[c] electron density maps for the fucose complex (A) and the fucosyl-enzyme intermediate (B) at 2.8 and 2.25 Å, respectively. Phases were calculated prior to incorporation of the ligand in the refinement, and the maps were contoured at 1.0 . Also shown is a schematic summarizing the interactions between TM aFuc and fucose (C). The ligand is shown in boldface, hydrogen bonds are shown as dashed lines, and van der Waals contacts are shown as pink dotted lines.
Figure 2.
FIG. 2. Overall view of TM aFuc. A, stereo ribbon diagram colored in a gradient along the TM aFuc amino acid sequence, from the N terminus (blue) to the C terminus (red). Secondary structure elements corresponding to the classical ( / )[8]-fold are indicated. The catalytic nucleophile Asp224 and the acid/base Glu266 are shown in ball-and-stick presentation, with carbon atoms colored gray and oxygen atoms colored red. B, the hexameric assembly of TM aFuc, as seen from the top (left) and rotated by 90° (right). For clarity, the trimers composing the hexamer are colored magenta and white, and one trimer is highlighted by a transparent surface representation. Bound fucose molecules are shown in green.

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 codes are shown on the right.
