gbuA

Gene
gbuA
Protein
Glycine betaine/carnitine transport ATP-binding protein GbuA
Organism
Listeria monocytogenes serotype 1/2a (strain 10403S)
Length
397 amino acids
Function
Part of the ABC transporter complex GbuABC involved in glycine betaine uptake. Responsible for energy coupling to the transport system. Involved, with BetL and OpuC, in osmoprotection and cryoprotection of Listeria. Can also uptake carnitine when carnitine is abundant in the growth medium.
Similarity
Belongs to the ABC transporter superfamily.
