Template:STRUCTURE 3v97

Crystal structure of bifunctional methyltransferase YcbY (RlmLK) from Escherichia coli, SAH binding

Template:ABSTRACT PUBMED 22362734

Function

[RLMKL_ECOLI] Specifically methylates the guanine in position 2445 (m2G2445) and the guanine in position 2069 (m7G2069) of 23S rRNA. Methylation occurs before assembly of 23S rRNA into 50S subunits.[1] [2] [3]

About this Structure

3v97 is a 2 chain structure with sequence from Escherichia coli k-12. Full crystallographic information is available from OCA.
