This domain is found in Aca2 repressor from Pectobacterium phage ZF40, the uncharacterised protein YdiL from Escherichia coli and related sequences. Aca2 regulates the transcription and translation of phage anti-CRISPR acrIF8 gene through DNA binding and translationally by binding conserved RNA stem-loops on mRNAs. This protein contains six alpha-helices and two parallel beta-strands [1-3].	Domain
