Also known as
cse2; ECK2754; ygcK
Summary
The Cascade antiviral complex is comprised of CasABCDE and short CRISP RNAs (crRNAs) and requires the predicted helicase YgcB(Cas3) for activity (Brouns , 2008). [More information is available at EcoGene: EG13118]. An insertion mutant in casB/ygcK shows lower transposition of IS903 . [More information is available at EcoCyc: G7429].
