Ribosome biogenesis is an energetically expensive and complex cellular process that involves the coordinated folding of the ribosomal RNA and dozens of ribosomal proteins. It proceeds along multiple parallel pathways and is guided by trans-acting factors called ribosome assembly factors. Although this process has been studied for decades, there are still many open questions regarding the role of the ribosome assembly factors in directing the folding of ribosome biogenesis intermediates. RimP is one of the early acting factors and guides the assembly of the small 30S ribosomal subunit by facilitating the binding of ribosomal proteins uS5 and uS12. Here we report the virtually complete 1H, 15N, and 13C chemical shift assignment of RimP from Escherichia coli. The NMR chemical shift data, deposited in the BMRB data bank under Accession No. 28014, indicates a widely folded protein composed of three alpha helices and eight beta strands.
