CRYSTAL STRUCTURE OF S. CEREVISIAE YNR046W, A ZINC FINGER PROTEIN FROM THE ERF1 METHYLTRANSFERASE COMPLEX.
Overview
Protein release factor eRF1 in Saccharomyces cerevisiae, in complex with, eRF3 and GTP, is methylated on a functionally crucial Gln residue by the, S-adenosylmethionine-dependent methyltransferase Ydr140w. Here we show, that eRF1 methylation, in addition to these previously characterized, components, requires a 15-kDa zinc-binding protein, Ynr046w. Co-expression, in Escherichia coli of Ynr046w and Ydr140w allows the latter to be, recovered in soluble form rather than as inclusion bodies, and the two, proteins co-purify on nickel-nitrilotriacetic acid chromatography when, Ydr140w alone carries a His tag. The crystal structure of Ynr046w has been, determined to 1.7 A resolution. It comprises a zinc-binding domain built, from both the N- and C-terminal sequences and an inserted domain, ...
