Crystal structure of yeast ymx7, an ADP-ribose-1-monophosphatase, complexed with ADP-ribose


Overview

Appr-1-pase, an important and ubiquitous cellular processing enzyme involved in the tRNA splicing pathway, catalyzes the conversion of ADP-ribose-1monophosphate (Appr-1-p) to ADP-ribose. The structures of the native enzyme from the yeast and its complex with ADP-ribose were determined to 1.9 A and 2.05 A, respectively. Analysis of the three-dimensional structure of this protein, selected as a target in a structural genomics project, reveals its putative function and provides clues to the catalytic mechanism. The structure of the 284-amino acid protein shows a two-domain architecture consisting of a three-layer alphabetaalpha sandwich N-terminal domain connected to a small C-terminal helical domain. The structure of Appr-1-pase in complex with the product, ADP-ribose, reveals an active-site water molecule poised for nucleophilic attack on the terminal phosphate group. Loop-region residues Asn 80, Asp 90, and His 145 may form a catalytic triad.
