PMID:17116241

Uncoupling of choline-O-sulphate utilization from osmoprotection in Pseudomonas putida.

A KT2440 betC deletion did not prevent accumulation of intact choline-O-sulfate.

"This mutant still accumulated intact COS but failed to use this compound as carbon or nitrogen source."

PMID:21369825

Inducible expression of choline sulfatase and its regulator BetR in Pseudomonas sp. ATCC19151.

The syntenic BetE homolog is predicted to be a STAS-domain permease.

"BetE is a permease and contains STAS domain."
