Note(s): Expression of sdiA is inhibited by glucose |CITS:[18560382]|.
Both sdiA and rcsA are involved in acyl-homoserine lactone (AHL)-mediated induction of the prophage process, and this induction is RecA independent |CITS:[19783745]|. Based on analysis with mutants, sdiA does not have any direct negative or positive regulatory role in rcsA expression, and the data suggest that intermediate transducers are involved in carrying the AHL-SdiA-mediated signal to activate rcsA for prophage induction |CITS:[19783745]|.
Evidence: [ICWHO] Inferred computationally without human oversight
