Efflux of choline and glycine betaine from osmoregulating cells of Escherichia coli.

FEMS microbiology letters - 15 Sept 1992

Lamark T, Styrvold O B, Strøm A R

Abstract excerpt

We present evidence that glycine betaine (betaine) which was synthesized from choline was excreted and reaccumulated in osmoregulating cells of Escherichia coli. Choline which was accumulated in bet mutants defective in betaine synthesis was shown to be excreted in response to betaine uptake. Our data suggest that E. coli has efflux systems for betaine and choline which are independent of the uptake systems for...
