Enolase-superfamily, characterized by the presence of an enolate anion intermediate which is generated by abstraction of the alpha-proton of the carboxylate substrate by an active site residue and is stabilized by coordination to the essential Mg2+ ion. Enolase superfamily contains different enzymes, like enolases, glutarate-, fucanate- and galactonate dehydratases, o-succinylbenzoate synthase, N-acylamino acid racemase, L-alanine-DL-glutamate epimerase, mandelate racemase, muconate lactonizing enzyme and 3-methylaspartase.

dimerization/docking (D/D) domain found in enolase 4 and similar proteins; Enolase (EC 4.2.1.11), also known as phosphopyruvate hydratase, is a metalloenzyme responsible for the catalyzing the conversion of 2-phosphoglycerate (2-PG) to phosphoenolpyruvate (PEP), the ninth and penultimate step of glycolysis. ENO4, also called 2-phospho-D-glycerate hydro-lyase, may be required for sperm motility and function. It contains an N-terminal domain which shows high sequence similarity to the dimerization/docking (D/D) domain of regulatory subunit of cAMP-dependent protein kinase (PKA) and protein DPY-30/SDC1.

dimerization/docking (D/D) domain of the type II Regulatory subunit of cAMP-dependent protein kinase and similar domains; cAMP-dependent protein kinase (PKA) is a serine/threonine kinase (STK), catalyzing the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The inactive PKA holoenzyme is a heterotetramer composed of two phosphorylated and active catalytic subunits with a dimer of regulatory (R) subunits. Activation is achieved through the binding of the important second messenger cAMP to the R subunits, which leads to the dissociation of PKA into the R dimer and two active subunits. There are two classes of R subunits, RI and RII; each exists as two isoforms (alpha and beta) from distinct genes. These functionally non-redundant R isoforms allow for specificity in PKA signaling. The R subunit contains an N-terminal dimerization/docking (D/D) domain, a linker with an inhibitory sequence (IS), and two c-AMP binding domains. RI and RII subunits are distinguished by their IS; RII subunits contain a phosphorylation site and are both substrates and inhibitors while RI subunits are pseudo-substrates. RI subunits require ATP and Mg ions to form a stable holoenzyme while RII subunits do not. The D/D domain dimerizes to form a four-helix bundle that serves as a docking site for A-kinase-anchoring proteins (AKAPs), which facilitates the localization of PKA to specific sites in the cell. PKA is present ubiquitously in cells and interacts with many different downstream targets. It plays a role in the regulation of diverse processes such as growth, development, memory, metabolism, gene expression, immunity, and lipolysis.

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.

(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
