The predicted Trg1 model closely resembles that of OmpR, particularly in the putative DNA binding region (α3 helix). Notably, the predicted Trg1 structure for the putative RNA polymerase interaction site (α-αloop, red) more closely matches that of PhoB. The phosphorylation site is shown as a purple sphere
