Prokaryotic large ribosomal subunit is an important structural component present in prokaryotic cells. Synonyms for this term include 50S ribosomal subunit, big ribosomal subunit, and bacterial large ribosomal subunit. This subunit plays a crucial role in protein synthesis in prokaryotic cells by catalyzing peptide bond formation. Other synonyms for this component include 23S RNA and 5S RNA, which are both important components of the large ribosomal subunit. As a key part of the ribosome, the prokaryotic large ribosomal subunit is essential for normal cellular function and survival. Its importance cannot be overstated, and it is a critical topic of study in the field of microbiology.
