This entry includes bacterial transcriptional regulators, such as glycerol operon regulatory protein and acetate operon repressor both of which are members of the iclR family [1,2]. These proteins have a Helix-Turn-Helix motif at the N-terminus. However this domain covers the C-terminal region that binds to regulatory substrates including Glyoxylate, allantoin/ate, indole, aromatic hydrocarbons, sugar acids, succinic semialdehyde, benzoate derivatives, ascorbic acid, glycerol-3-phosphate, glyceraldehyde-3-phosphate and pyruvate [3].
