Structural aspects of RimP binding on small ribosomal subunit from Staphylococcus aureus. Structure 2024; 32:74-82.e5.

Abstract
Ribosome biogenesis is an energy-intense multistep process where even minimal defects can cause severe phenotypes up to cell death. Ribosome assembly is facilitated by biogenesis factors such as ribosome assembly factors. These proteins facilitate the interaction of ribosomal proteins with rRNA and correct rRNA folding. One of these maturation factors is RimP which is required for efficient 16S rRNA processing and 30S ribosomal subunit assembly. Here, we describe the binding mode of Staphylococcus aureus RimP to the small ribosomal subunit and present a 4.2 Å resolution cryo-EM reconstruction of the 30S-RimP complex. Together with the solution structure of RimP solved by NMR spectroscopy and RimP-uS12 complex analysis by EPR, DEER, and SAXS approaches, we show the specificity of RimP binding to the 30S subunit from S. aureus. We believe the results presented in this work will contribute to the understanding of the RimP role in the ribosome assembly mechanism.

Abstract
Antibiotic‐resistant Staphylococcus aureus is becoming a major burden on health care systems in many countries, necessitating the identification of new targets for antibiotic development. Elongation Factor P (EF‐P) is a highly conserved elongation protein factor that plays an important role in protein synthesis and bacteria virulence. EF‐P undergoes unique posttranslational modifications in a stepwise manner to function correctly, but experimental information on EF‐P posttranslational modifications is currently lacking for S. aureus. Here, we expressed EF‐P in S. aureus to analyze its posttranslational modifications by mass spectrometry and report experimental proof of 5‐aminopentanol modification of S. aureus EF‐P.
