== Function ==
[https://www.uniprot.org/uniprot/ERM_STREE ERM_STREE] This protein produces a dimethylation of the adenine residue at position 2085 in 23S rRNA, resulting in reduced affinity between ribosomes and macrolide-lincosamide-streptogramin B antibiotics.

== Publication Abstract from PubMed ==
The Erm family of methyltransferases is responsible for the development of resistance to the macrolide-lincosamide-streptogramin type B (MLS) antibiotics. These enzymes methylate an adenine of 23S ribosomal RNA that prevents the MLS antibiotics from binding to the ribosome and exhibiting their antibacterial activity. Here we describe the three-dimensional structure of an Erm family member, ErmAM, as determined by NMR spectroscopy. The catalytic domain of ErmAM is structurally similar to that found in other methyltransferases and consists of a seven-stranded beta-sheet flanked by alpha-helices and a small two-stranded beta-sheet. In contrast to the catalytic domain, the substrate binding domain is different from other methyltransferases and adopts a novel fold that consists of four alpha-helices.
