Ribosomal RNA large subunit methyltransferase M, N-terminal

Date:: 2024-08-14

Family Accession:: NF045326.2
Method:: HMM

Select item 4285082.

This domain is found in Ribosomal methyltransferase RlmM (YdgE) present in E. coli. RlmM catalyzes the S-adenosyl methionine (AdoMet)-dependent 2'O methylation of C2498 in 23S ribosomal RNA. The domain is ferredoxin-like and forms part of the THUMP domain which binds RNA. THUMP domains typically have low sequence similarity [1]. [1]. 22923526.

SAM-dependent methyltransferase

This family consists of FtsJ from various bacterial and archaeal sources FtsJ is a methyltransferase, but actually has no effect on cell division. FtsJ's substrate is the 23S rRNA. The 1.5 A crystal structure of FtsJ in complex with its cofactor S-adenosylmethionine revealed that FtsJ has a methyltransferase fold. This family also includes the N terminus of flaviviral NS5 protein. It has been hypothesised that the N-terminal domain of NS5 is a methyltransferase involved in viral RNA capping [2]. [1]. 10983982.
