This highly conserved ribonucleoprotein domain is the target for the thiostrepton family of antibiotics that disrupt elongation factor function. The highly compact RNA has both familiar and novel structural motifs. While the C-terminal domain of L11 binds RNA tightly, the N-terminal domain makes only limited contacts with RNA and is proposed to function as a switch that reversibly associates with an adjacent region of RNA. The sites of mutations conferring resistance to thiostrepton and micrococcin line a narrow cleft between the RNA and the N-terminal domain. These antibiotics are proposed to bind in this cleft, locking the putative switch and interfering with the function of elongation factors. #2: ジャーナル: Science / 年: 1999 タイトル: Crystal Structure of a Conserved Ribosomal Protein-RNA Complex 著者: Conn, G.L. / Draper, D.E. / Lattman, E.E. / Gittis, A.G. | |||||||||

THE NOES INCLUDED IN THE RESTRAINTED MODELING WERE OBTAINED FROM A FILTERED NOESY EXPERIMENT ON A COMPLEX OF UNLABELED THIOSTREPTON WITH THE RNA. AS ALL INTERNAL COORDINATES WERE HELD RIGID ACCORDING TO THE X-RAY STRUCTURES, ONLY INTERMOLECULAR NOES WERE INCLUDED. ASSIGNMENTS FOR RNA WERE CHOSEN FROM AN ITERATIVE DOCKING PROCESS (SEE LENTZEN ET AL AND MANUSCRIPT TO BE PUBLISHED) |
