A streamlined ribosome profiling protocol for the characterization of microorganisms.

Area of Science:

• Molecular Biology
• Genomics
• Microbiology

Background:

• Ribosome profiling is a powerful genome-scale technique for studying protein translation in vivo.
• Its complexity has limited widespread adoption in the microbial research community.
• Existing protocols are time-consuming and have high barriers to entry.

Purpose of the Study:

• To present a streamlined ribosome profiling protocol tailored for microbial characterization.
• To reduce the complexity and time investment required for ribosome profiling.
• To increase the accessibility of ribosome profiling for microbial research.

Main Methods:

• Developed simplified procedures for cell harvest, lysis, and monosome recovery.
• Eliminated time-consuming library construction steps, including size selection.
• Optimized the protocol to significantly reduce ribosomal RNA (rRNA) and transfer RNA (tRNA) contamination.

Main Results:

• Achieved a streamlined workflow reducing the time from sample harvest to final library preparation to 3-4 days.
• Demonstrated significantly reduced abundance of rRNAs and tRNAs in the final sequencing library.
• Maintained high data quality with a high fraction of informative reads, comparable to existing protocols.

Conclusions:

• The streamlined ribosome profiling protocol lowers barriers to entry for microbial studies.
• This optimized method enables higher throughput and faster characterization of in vivo protein translation.
• The protocol retains high quality standards while significantly reducing hands-on time and complexity.
