Type II methyltransferase M.RsrI

Gene:

rsrIM Enzyme: EC 2.1.1.72 This enzyme has known catalytic activity involved in reaction: a 2'-deoxyadenosine in DNA + S-adenosyl-L-methionine = an N(6)-methyl-2'-deoxyadenosine in DNA + S-adenosyl-L-homocysteine + H(+)

Organism:

Cereibacter sphaeroides (Rhodobacter sphaeroides)

Uniprot:

P14751go to UniProt

Biological function:

A beta subtype methylase, recognizes the double-stranded sequence 5'-GAATTC-3', methylates A-3 on both strands, and protects the DNA from cleavage by the RsrI endonucleasego to UniProt

PDB chain with highest data quality, coverage and best resolution This viewer shows non-overlapping chains from PDB entries with the highest number of observed residues for various regions of the UniProt protein sequence.

Use the arrows or click on the blue segments at the bottom to navigate between representative chains from different PDB entries for different regions of the sequence.

Observed regions are darker shades, while unobserved regions are slightly transparent.
