Summary: ADP-specific Phosphofructokinase/Glucokinase conserved region

Pfam includes annotations and additional family information from a range of different sources. These sources can be accessed via the tabs below.

The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.

This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.

ADP-specific Phosphofructokinase/Glucokinase conserved region Provide feedback

In archaea a novel type of glycolytic pathway exists that is deviant from the classical Embden-Meyerhof pathway. This pathway utilises two novel proteins: an ADP-dependent Glucokinase and an ADP-dependent Phosphofructokinase. This conserved region is present at the C-terminal of both these proteins. Interestingly this family contains sequences from higher eukaryotes. [1,2,3].

InterPro entry IPR007666

Although ATP is the most common phosphoryl group donor for kinases, certain hyperthermophilic archaea, such as Thermococcus litoralis and Pyrococcus furiosus, utilise unusual ADP-dependent glucokinases (ADPGKs) and phosphofructokinases (ADPPKKs) in their glycolytic pathways [ PUBMED:11286887 , PUBMED:12237466 , PUBMED:12909015 ]. ADPGKs and ADPPFKs exhibit significant similarity, and form an ADP-dependent kinase (ADPK) family, which was tentatively named the PFKC family [ PUBMED:11778837 ]. A ~460-residue ADPK domain is also found in a bifunctional ADP-dependent gluco/phosphofructo- kinase (ADP-GK/PFK) from Methanocaldococcus jannaschii (Methanococcus jannaschii) as well as in homologous hypothetical proteins present in several eukaryotes [ PUBMED:11717273 ].

The whole structure of the ADPK domain can be divided into large and small alpha/beta subdomains. The larger subdomain, which carries the ADP binding site, consists of a twisted 12-stranded beta sheet flanked on both faces by 13 alpha helices and three 3(10) helices, forming an alpha/beta 3-layer sandwich. The smaller subdomain, which covers the active site, forms an alpha/beta two-layer structure containing 5 beta strands and four alpha helices. The ADP molecule is buried in a shallow pocket in the large subdomain. The binding of substrate sugar induces a structural change, the small domain closing to form a complete substrate sugar binding site [ PUBMED:11286887 , PUBMED:12237466 , PUBMED:12909015 ].

Pfam Clan

This family is a member of clan Ribokinase (CL0118), which has the following description:

All of these enzymes are phosphotransferases that have an alcohol group as an acceptor (EC:2.7.1.-). However, 4-amino-5-hydroxymethyl-2-methylpyrimidine phosphate kinase (HMPP kinase) catalyses two phosphorylation reactions: one to a hydroxymethyl group of hydroxymethyl pyrimidine (HMP) and the second to the phosphomethyl group of HMPP [1]. The common structural feature for the enzymes in this superfamily is a central eight-stranded sheet that is flanked by eight structurally conserved helices, five on one side and three on the other [1]. The active site is located in a shallow groove along one edge of the sheet, with the phosphate acceptor hydroxyl group and -phosphate of ATP close together in the middle of the groove, and substrate and ATP binding at the ends [1].

The clan contains the following 5 members:

ADP_PFK_GK Carb_kinase HK PfkB Phos_pyr_kin


We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database (reference proteomes) using the family HMM. We also generate alignments using four representative proteomes (RP) sets and the UniProtKB sequence database. More...

View options

We make a range of alignments for each Pfam-A family. You can see a description of each above. You can view these alignments in various ways but please note that some types of alignment are never generated while others may not be available for all families, most commonly because the alignments are too large to handle.

HMM logos is one way of visualising profile HMMs. Logos provide a quick overview of the properties of an HMM in a graphical form. You can see a more detailed description of HMM logos and find out how you can interpret them here. More...


This page displays the phylogenetic tree for this family's seed alignment. We use FastTree to calculate neighbour join trees with a local bootstrap based on 100 resamples (shown next to the tree nodes). FastTree calculates approximately-maximum-likelihood phylogenetic trees from our seed alignment.

Note: You can also download the data file for the tree.

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the ADP_PFK_GK domain has been found. There are 22 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein sequence.
