nucleotide-binding domain (NBD) of metazoan glycerol kinase 5 (GK5) and similar proteins; The subfamily corresponds to a group of metazoan putative glycerol kinases (GK), which may be coded by the GK-like gene, GK5. Sequence comparison shows members of this group are homologs of bacterial GKs, and they retain all functionally important residues. However, GK-like proteins in this family do not have detectable GK activity. The reason remains unclear. It has been suggested that the conserved catalytic residues might facilitate them performing a distinct function. GK5 is a skin-specific kinase expressed predominantly in sebaceous glands. It can form a complex with the sterol regulatory element-binding proteins (SREBPs) through their C-terminal regulatory domains, inhibiting SREBP processing and activation. GK5 also promotes gefitinib resistance by inhibiting apoptosis and cell cycle arrest.

Sequence comparison shows that metazoan GKs and GK-like proteins in this family are closely related to the bacterial GKs (EC 2.7.1.30), which catalyze the Mg-ATP dependent phosphorylation of glycerol to yield glycerol 3-phosphate (G3P). The metazoan GKs do have GK enzymatic activity. However, the GK-like metazoan proteins do not exhibit GK activity and their biological functions are not yet clear. Some of them lack important functional residues involved in the binding of ADP and Mg2+, which may result in the loss of GK catalytic function.

GKs contain two large domains separated by a deep cleft that forms the active site. This model includes both the N-terminal domain, which adopts a ribonuclease H-like fold, and the structurally related C-terminal domain. The high affinity ATP binding site of EcGK is created only by a substrate-induced conformational change, which is initiated by protein-protein interactions through complex formation with enzyme IIAGlc (also known as IIIGlc), the glucose-specific phosphocarrier protein of the phosphotransferase system (PTS). EcGK exists in a dimer-tetramer equilibrium. IIAGlc binds to both EcGK dimer and tetramer, and inhibits the uptake and subsequent metabolism of glycerol and maltose. Another well-known allosteric regulator of EcGK is fructose 1,6-bisphosphate (FBP), which binds to the EcGK tetramer and plays an essential role in the stabilization of the inactive tetrameric form. EcGK requires Mg2+ for its enzymatic activity. Members in this subgroup belong to the FGGY family of carbohydrate kinases

of the residues that compose this conserved feature have been mapped to the query sequence.
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.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

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
(labeled illustration).
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.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(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)
the domain superfamily to which the specific and non-specific hits belong
multi-domain models that were computationally detected and are likely to contain multiple single domains
Retrieve proteins that contain one or more of the domains present in the query sequence, using the Conserved Domain Architecture Retrieval Tool
(CDART).
