Structural highlights

Function

TRMBR_PYRFU Inhibits transcription of the trehalose/maltose transport gene cluster (malE operon) and of the maltodextrin transport gene cluster (mdxE operon). Acts by binding to two different operator sequences in both promoters, preventing polymerase recruitment and transcription.^{[1] [2]}
