23S rRNA (adenine1618-N6)-methyltransferase (EC 2.1.1.181, rRNA large subunit methyltransferase F, YbiN protein, rlmF (gene), m6A1618 methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:23S rRNA (adenine1618-N6)-methyltransferase.[1] This enzyme catalyses the following chemical reaction

S-adenosyl-L-methionine + adenine1618 in 23S rRNA [math]\displaystyle{ \rightleftharpoons }[/math] S-adenosyl-L-homocysteine + N6-methyladenine1618 in 23S rRNA

The recombinant YbiN protein is able to methylate partially deproteinized 50 S ribosomal subunit.
