Two recent papers from Doudna and Marletta groups combine SAXS with Cryo-EM

The Doudna group, explained in their recent paper,  “Structural basis for AcrVA4 inhibition of specific CRISPR-Cas12a” combine SAXS with Cryo-Em to show the C-terminal binding domain is sufficient for Cas12a inhibition. CRISPR-Cas systems provide bacteria and archaea with programmable immunity against mobile genetic elements. Evolutionary pressure by CRISPR-Cas has driven bacteriophage to evolve small protein…
