YjeF-N domain is a novel version of the Rossmann fold with a set of catalytic residues and structural features that are different from the conventional dehydrogenases [1]. YjeF-N domain is fused to Ribokinases in bacteria (YjeF), where they may be phosphatases, and to divergent Sm and the FDF domain in eukaryotes (Dcp3p and FLJ21128) [1], where they may be involved in decapping and catalyze hydrolytic RNA-processing reactions [1].
