This is the N-terminal domain of the RsmF methyl transferase. RsmF is a multi-site-specific methyltransferase that is responsible for the synthesis of three modifications on cytidines in 16S ribosomal RNA. The N-terminus is critical for stabilising the catalytic core of the enzyme [1]. It has a ferredoxin-like fold.
This is the catalytic core of this SAM-dependent 16S ribosomal methyltransferase RsmB/F enzyme [1,2]. There is a catalytic cysteine residue at 180 in UniProtKB:Q5SII2, with another highly conserved cysteine at residue 230. It methylates the C(5) posi ...
This is the catalytic core of this SAM-dependent 16S ribosomal methyltransferase RsmB/F enzyme [1,2]. There is a catalytic cysteine residue at 180 in UniProtKB:Q5SII2, with another highly conserved cysteine at residue 230. It methylates the C(5) position of cytosine 2870 (m5C2870) in 25S rRNA [1,2].
Ribosomal RNA small subunit methyltransferase F, pre-PUA domain
This domain is found in Ribosomal RNA small subunit methyltransferase F from Escherichia coli (YebU) and similar proteins mainly from proteobacteria. YebU requires S-adenosyl-l-methionine (SAM) to specifically methylate the cytosine at position 1407 ...
This domain is found in Ribosomal RNA small subunit methyltransferase F from Escherichia coli (YebU) and similar proteins mainly from proteobacteria. YebU requires S-adenosyl-l-methionine (SAM) to specifically methylate the cytosine at position 1407 of assembled 30 S rRNA subunits. This proteins is organized into two distinct structural domains: the N-terminal MTase domain (catalytic domain), which can be divided in Pfam:PF17125 and Pfam:PF01189, and the C-terminal, also consisting of two subdomains. This entry represents the first of these subdomains, which is found N-terminal to the PUA- like domain (Pfam:PF13636). The pre-PUA domain has six beta-strands that form a central sheet in an anti-parallel fashion, and three alpha-helices packing against the edges of the sheet [1].
