CRYSTAL STRUCTURE OF RHODOBACTER SPHEROIDES (N6 ADENOSINE) METHYLTRANSFERASE (M.RSRI)CRYSTAL STRUCTURE OF RHODOBACTER SPHEROIDES (N6 ADENOSINE) METHYLTRANSFERASE (M.RSRI)

Structural highlights

1eg2 is a 1 chain structure with sequence from Cereibacter sphaeroides. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 1.75Å
Ligands:
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT, TOPSAN

Function

MTR1_CERSP 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 endonuclease.[1] [2]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
