The Mar proteins are involved in the multiple antibiotic resistance, a non-specific resistance system. The expression of the mar operon is controlled by a repressor, MarR. A large number of compounds induce transcription of the mar operon. This is thought to be due to the compound binding to MarR, and the resulting complex stops MarR binding to the DNA. With the MarR repression lost, transcription of the operon proceeds [1]. The structure of MarR is known [2] and shows MarR as a dimer with each subunit containing a winged-helix DNA binding motif.

This is the AlbA_2 domain from the Schlafen (SLFN) family of proteins which are important in cell differentiation and defense against viruses [1,2]. This domain is present at the N-terminal of all SLFN proteins and includes the SLFN box, a sequence unique to these proteins that may form a dimer interface [1]. The AlbA_2 domain is RNA-binding and RNase region as it contains the highly conserved catalytic glutamic acid residues [1]. [1]. 31026779.
