== Function ==
[https://www.uniprot.org/uniprot/RL2_HALMA RL2_HALMA] One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome (By similarity).[HAMAP-Rule:MF_01320_A]

== Publication Abstract from PubMed ==
We have developed a first generation of hybrid sparsomycin-linezolid compounds into a new family of orally bioavailable biaryloxazolidinones that have activity against both linezolid-susceptible and -resistant gram-positive bacteria as well as the fastidious gram-negative bacteria Haemophilus influenzae and Moraxella catarrahalis. The convergent synthesis of these new compounds is detailed.

Design at the atomic level: design of biaryloxazolidinones as potent orally active antibiotics.,Zhou J, Bhattacharjee A, Chen S, Chen Y, Duffy E, Farmer J, Goldberg J, Hanselmann R, Ippolito JA, Lou R, Orbin A, Oyelere A, Salvino J, Springer D, Tran J, Wang D, Wu Y, Johnson G Bioorg Med Chem Lett. 2008 Dec 1;18(23):6175-8.
