 1-135 5.65e-74

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 catalyzes the di-methylation of ribosomal proteins Rpl12 and Rps25 at N-terminal proline residues. The methyltransferases described here specifically recognize 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. As with other methyltransferases, this family carries the characteriztic GxGxG motif.

S-adenosylmethionine-dependent methyltransferases (SAM or AdoMet-MTase), class I; AdoMet-MTases are enzymes that use S-adenosyl-L-methionine (SAM or AdoMet) as a substrate for methyltransfer, creating the product S-adenosyl-L-homocysteine (AdoHcy). There are at least five structurally distinct families of AdoMet-MTases, class I being the largest and most diverse. Within this class enzymes can be classified by different substrate specificities (small molecules, lipids, nucleic acids, etc.) and different target atoms for methylation (nitrogen, oxygen, carbon, sulfur, etc.).
