This family appears to be a methyltransferase domain. (from Pfam)
methyltransferase
Members of this family are SAM dependent methyltransferases. (from Pfam)
AdoMet dependent proline di-methyltransferase
This protein is expressed in the tail neuron PVT and in uterine cells in C. elegans [worm-base]. In Saccharomyces cerevisiae this is AdoMet dependent proline di-methyltransferase. This enzyme catalyses the di-methylation of ribosomal proteins Rpl12 and Rps25 at N-terminal proline residues. The methyltransferases described here specifically recognise the N-terminal X-Pro-Lys sequence motif, and they may account for nearly all previously described eukaryotic protein N-terminal methylation reactions. A number of other yeast and human proteins also share the recognition motif and may be similarly modified [1]. As with other methyltransferases, this family carries the characteristic GxGxG motif.

class I SAM-dependent methyltransferase
Protein-L-isoaspartate(D-aspartate) O-methyltransferase (PCMT)
