The protein

Catalyzed reaction/ biological activity

• binds opuAA, tapA, and epsA promoter regions (upstream of the actual promoter) to activate transcription [Pubmed|23646920]
• binds DNA with high co-operativity due to low conserrvation of binding sites [Pubmed|23646920]

Protein family

• RemA family (single member, according to UniProt)
