CC -!- FUNCTION: Repressor involved in choline regulation of the bet genes.
CC {ECO:0000256|HAMAP-Rule:MF_00768}.
CC -!- FUNCTION: Repressor involved in the biosynthesis of the osmoprotectant
CC glycine betaine. It represses transcription of the choline transporter
CC BetT and the genes of BetAB involved in the synthesis of glycine
CC betaine. {ECO:0000256|ARBA:ARBA00024936}.
CC -!- PATHWAY: Amine and polyamine biosynthesis; betaine biosynthesis via
CC choline pathway [regulation]. {ECO:0000256|ARBA:ARBA00004719,
CC ECO:0000256|HAMAP-Rule:MF_00768}.
