| Type: | Domain | Name: | SAM-binding methyltransferase MPBQ/MBSQ |
| Description: | This entry represents a domain found in a subgroup of the SAM-binding methyltransferase family. Proteins containing this domain include MPBQ/MSBQ methyltransferase from plants []. Methyl transfer from the ubiquitous S-adenosyl-L-methionine (SAM) to either nitrogen, oxygen or carbon atoms is frequently employed in diverse organisms ranging from bacteria to plants and mammals. The reaction is catalyzed by methyltransferases (Mtases) and modifies DNA, RNA, proteins and small molecules, such as catechol for regulatory purposes. The various aspects of the role of DNA methylation in prokaryotic restriction-modification systems and in a number of cellular processes in eukaryotes including gene regulation and differentiation is well documented. | Short Name: | SAM_MPBQ_MSBQ_MT |
