This domain is found in various prokaryotic proteins, including cell wall-active antibiotic response proteins. This entry includes protein product of the yvqF gene, LiaF, located immediately upstream of vraS. It is associated with glycopeptide resistance in Staphylococcus aureus [2]. This domain has been described as toast rack from its structural resemblance.
