Function

RS2_THET8 Spans the head-body hinge region of the 30S subunit. Is loosely associated with the 30S subunit.[HAMAP-Rule:MF_00291_B]

Publication Abstract from PubMed

The ribosome is the target of a large number of antibiotics. Here, we report a 3.4-A-resolution crystal structure of bactobolin A bound to 70S ribosome-tRNA complex. The antibiotic binds at a previously unseen site in the 50S subunit and displaces tRNA bound at the P-site. It thus likely has a similar mechanism of action as blasticidin S despite binding to a different site. The structure also rationalizes previously identified resistance mutations.
