Originally isolated from the bacterium *Streptomyces alboniger*, the aminonucleoside antibiotic puromycin is primarily known for its potent ability to inhibit protein synthesis in both prokaryotic and eukaryotic cells, a discovery that has made it an indispensable tool for molecular and cellular biology research.

Did you know that thromboxanes are potent lipid mediators primarily produced by platelets that are essential for blood clotting and wound healing? However, this same process can become pathological, making it crucial to understand **what do thromboxanes do** in the body and how their function impacts overall health.

In many pathogenic viruses, such as Coronaviridae and Flaviviridae, large polyproteins are cleaved to produce the final functional molecules [1.6.7]. A key product of this process is the **mat peptide**, or mature peptide, which is the final, biologically active form of a peptide after all post-translational modifications are complete [1.3.4].
