Multi-domain repressor protein that negatively regulates transcription of the quinate utilization pathway genes. May mediate its repressor activity by binding directly to the qa-1f activator protein (By similarity). Is homologous throughout its length with the C-terminal 3 domains of the pentafunctional AROM protein. The function of the 2 C-terminal domains may be to act as a molecular sensor that detects the presence of quinate pathway intermediates as a prerequisite for the presumed conformational changes necessary for the control of transcription regulation (By similarity). In the N-terminal section; belongs to the shikimate kinase family. In the 2nd section; belongs to the type-I 3-dehydroquinase family. In the C-terminal section; belongs to the shikimate dehydrogenase family.
