A	PF18125	RlmM ferredoxin-like domain (RlmM_FDX)	RlmM ferredoxin-like domain	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 d ...	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].	Domain

A	PF21239	Ribosomal RNA large subunit methyltransferase M, N-terminal (RLMM_N)	Ribosomal RNA large subunit methyltransferase M, N-terminal	This is the THUMP-like domain of Ribosomal RNA large subunit methyltransferase M (RLMM), adjacent the ferredoxin-like domain (Pfam:PF18125), which together constitutes the N-terminal domain [1]. RlmM specifically catalyses the 2'-O-methylation of nuc ...	This is the THUMP-like domain of Ribosomal RNA large subunit methyltransferase M (RLMM), adjacent the ferredoxin-like domain (Pfam:PF18125), which together constitutes the N-terminal domain [1]. RlmM specifically catalyses the 2'-O-methylation of nucleotide C2498 in the peptidyl transferase loop of 23S rRNA [1].	Domain
