Model of transient srrY expression for LM and LC production in S. rochei. (A) SrrA represses both srrY and srrB expression in the early stage of growth. (B) Dissociation of SrrA from the promoter region of both srrY and srrB by SRB in middle stage of growth. (C) Repression of srrY by SrrB in the late stage of growth. Solid lines indicate the confirmed regulatory pathway hitherto. Additional dashed lines were suggested by unpublished results. Orange triangles indicate the signaling molecules SRBs.
