- S-adenozil-L-metionin + adenin1618 u 23S rRNK S-adenozil-L-homocistein + N6-metiladenin1618 u 23S rRNK
Rekombinantni YbiN protein ima sposobnost metilacije parcijalno deprotonisane 50 S ribozomalne podjedinice. On ne deluje na kompletno formirane 50 S podjednice, niti na kompletno deprotonisanu 23 S rRNK.
