| + | Elimination of the 5' cap of eukaryotic mRNAs, known as decapping, is considered to be a crucial, irreversible and highly regulated step required for the rapid degradation of mRNA by Xrn1, the major cytoplasmic 5'-3' exonuclease. Decapping is accomplished by the recruitment of a protein complex formed by the Dcp2 catalytic subunit and its Dcp1 cofactor. However, this complex has a low intrinsic enzymatic activity and requires several accessory proteins such as the Lsm1-7 complex, Pat1, Edc1-Edc2 and/or Edc3 to be fully active. Here we present the crystal structure of the active form of the yeast Kluyveromyces lactis Dcp1-Dcp2 enzyme bound to its product (m7GDP) and its potent activator Edc3. This structure of the Dcp1-Dcp2 complex bound to a cap analog further explains previously published data on substrate binding and provides hints as to the mechanism of Edc3-mediated Dcp2 activation. | ||
