Summary:The protein dimethyladenosine transferase 1 (Dim1) is a highly conserved protein occurring in organisms ranging from bacteria such as E. coli where it is named KsgA to humans. Since Dim1 is involved in the biogenesis of the small ribosomal subunit it is an essential protein. During ribosome biogenesis Dim1 acts as an rRNA modification enzyme and dimethylates two adjacent adenosine residues of the small ribosomal subunit rRNA. In eukaryotes it is also required to ensure the proper endonucleolytic processing of the small ribosomal subunit rRNA precursor. Recently, a third function was proposed for eukaryotic Dim1. Karbstein and coworkers suggested that Dim1 interacts with the essential ribosome assembly factor Fap7 and that Fap7 is responsible for the dissociation of Dim1 from the nascent small ribosomal subunit. Here, we report the backbone H, C and N NMR resonance assignments for the 30.9 kDa Dim1 homologue from the hyperthermophilic archaeon Pyrococcus horikoshii (PhDim1) as a prerequisite for a detailed structural investigation of the PhDim1/PhFap7 interaction.
