The Lord of the Rings: Cysteine bonds crosslink the tail of siphovirus

Long, non‐contractile tails composed of helical hexameric protein repeats that assemble into continuous tubular structures characterize siphoviruses. The siphovirus tail tube protein gp39 contains two cysteine residues per monomer. Cryo‐electron microscopy revealed that these cysteines are oriented toward the interface...

Building CRISPR immunity: evolution and mechanisms of spacer acquisition.

CRISPR-Cas systems in prokaryotes serve as adaptive immune systems that neutralize phage infections through RNA-guided nucleases. Immunization is achieved during the adaptation stage through Cas1-Cas2 integrase-mediated insertion of short foreign DNA snippets, termed spacers, into a CRISPR array in the host genome. Thi...
