26-299 4.57e-173

Substrate-binding domain OsmF of an osmoregulated ABC-type transporter; the type 2 periplasmic-binding protein fold; Osmoprotectant binding lipoprotein OsmF of an ABC transporter (YehZYXW) from Escherichia coli is predicted to be involved in uptake of compatible solutes such as choline, L-proline and glycine betaine, but the relative substrate preference is not known. To counteract the efflux of water, microorganisms accumulate the compatible solutes for a sustained adjustment to high osmolarity surroundings. OsmF belongs to the type 2 periplasmic binding fold protein superfamily (PBP2). The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

25-300 1.01e-56

Substrate binding domain of ABC-type glycine betaine transport system; Part of a high affinity multicomponent binding-protein-dependent transport system involved in bacterial osmoregulation. This domain is often fused to the permease component of the transporter complex. Family members are often integral membrane proteins or predicted to be attached to the membrane by a lipid anchor. Glycine betaine is involved in protection from high osmolarity environments for example in Bacillus subtilis. The family member OpuBC is closely related, and involved in choline transport. Choline is necessary for the biosynthesis of glycine betaine. L-carnitine is important for osmoregulation in Listeria monocytogenes. Family also contains proteins binding l-proline (ProX), histidine (HisX) and taurine (TauA).

26-299 2.49e-97

Substrate-binding domain of osmoregulatory ABC-type transporters; the type 2 periplasmic-binding protein fold; This family represents the periplasmic substrate-binding component of ABC transport systems that are involved in uptake of osmoprotectants (also termed compatible solutes) such as betaine, choline, proline betaine, carnitine, and L-proline. To counteract the efflux of water, bacteria and archaea accumulate the compatible solutes for a sustained adjustment to high osmolarity surroundings. This substrate-binding domain belongs to the type 2 periplasmic binding fold protein superfamily (PBP2). The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

26-299 8.44e-81

Substrate-binding domain YehZ of an osmoregulated ABC-type transporter; the type 2 periplasmic-binding protein fold; Osmoprotectant binding lipoprotein YehZ of Clostridium sticklandii is predicted to be involved in uptake of compatible solutes such as choline, L-proline and glycine betaine, but the relative substrate preference is not known. To counteract the efflux of water, microorganisms accumulate the compatible solutes for a sustained adjustment to high osmolarity surroundings. YehZ belongs to the type 2 periplasmic binding fold protein superfamily (PBP2). The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

25-300 1.01e-56

Substrate binding domain of ABC-type glycine betaine transport system; Part of a high affinity multicomponent binding-protein-dependent transport system involved in bacterial osmoregulation. This domain is often fused to the permease component of the transporter complex. Family members are often integral membrane proteins or predicted to be attached to the membrane by a lipid anchor. Glycine betaine is involved in protection from high osmolarity environments for example in Bacillus subtilis. The family member OpuBC is closely related, and involved in choline transport. Choline is necessary for the biosynthesis of glycine betaine. L-carnitine is important for osmoregulation in Listeria monocytogenes. Family also contains proteins binding l-proline (ProX), histidine (HisX) and taurine (TauA).

26-303 6.83e-45

Substrate-binding protein ProWX of ABC-type osmoregulated transporter and its related proteins; the type 2 periplasmic-binding protein fold; Osmoprotectant binding lipoprotein ProWX of Helicobacter pylori is predicted to be involved in uptake of compatible solutes such as choline, L-proline and glycine betaine, but the relative substrate preference is not known. To counteract the efflux of water, microorganisms accumulate the compatible solutes for a sustained adjustment to high osmolarity surroundings. ProWX belongs to the type 2 periplasmic binding fold protein superfamily (PBP2). The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.
