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).

Substrate binding domain of Lactococcus lactis ABC-type transporter OpuA and related proteins; the type 2 periplasmic binding protein fold; This subfamily is part of a high affinity multicomponent binding-protein-dependent transport system specific to betaine compounds for osmoregulation. The periplasmic substrate-binding domain, which is often fused to the permease component of the ATP-binding cassette transporter complex, is involved in uptake of osmoprotectants (also termed compatible solutes) such as glycine betaine and proline betaine. Many microorganisms accumulate these compatible solutes in response to high osmolarity to offset the loss of cell water. This 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.

Substrate binding domain of ABC-type choline transport system; the type 2 periplasmic binding protein fold; This subfamily is part of a high affinity multicomponent binding-protein-dependent transport system specific to choline and acetylcholine for osmoregulation. The periplasmic substrate-binding domain, which is often fused to the permease component of the ATP-binding cassette transporter complex, is involved in uptake of osmoprotectants (also termed compatible solutes) such as choline and betaines. Choline is necessary for the biosynthesis of glycine betaine. Many microorganisms accumulate these compatible solutes in response to high osmolarity to offset the loss of cell water. In the case of the Sinorhizobium meliloti choline uptake system ChoVWX, ChoV is the nucleotide-binding domain that provides energy for the transport process via ATP hydrolysis, ChoW is the integral transmembrane protein that forms the substrate translaocation pathway, and ChoX is the substrate-binding domain. ChoX 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.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits

Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
