Crystallization and preliminary crystallographic studies of the YafN–YafO complex from Escherichia coli

The ribosome-dependent mRNA interferase YafO from Escherichia coli belongs to a type II toxin–antitoxin (TA) system and its cognate antitoxin YafN neutralizes cell toxicity by forming a stable YafN–YafO complex. Here, the YafN–YafO complex has been expressed and crystallized.
