Putative model of acr gene repression by Aca2. (a) Structural comparison of monomeric osAca2 with monomeric MqsA by superimposition. The superimposed position showing the HTH motif of MqsA is labeled. (b) Structural comparison of dimeric osAca2 with the dimeric MqsA–DNA complex by superimposition. (c) Putative model of acr gene repression by Aca2. The tentative nucleotide sequence in the P1 promoter corresponding to osAca2 is highlighted in red and blue. |
