Glycine betaine transporter BetP

UniProtKB accession:  P54582

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in response to osmotic stress (PubMed:10625602, PubMed:19262666, PubMed:21364531, PubMed:24141878, PubMed:7642496, PubMed:9446558). High-affinity glycine betaine-specific uptake system, which couples the uptake of glycine betaine to the symport of two Na(+) ions (PubMed:10625602, PubMed:15134432, PubMed:19262666, PubMed:21364531, PubMed:22940865, PubMed:24141878, PubMed:7642496). Transport is driven both by the Na(+) gradient and by the electrical potential (PubMed:10625602, PubMed:7642496). In addition, functions both as an osmosensor and as an osmoregulator that transduces signal to the catalytic part of the carrier protein, which adapts its activity to the extent of osmotic stress (PubMed:10625602, PubMed:11574473, PubMed:9446558).
