Family: GFA (PF04828)

Summary: Glutathione-dependent formaldehyde-activating enzyme

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.

Glutathione-dependent formaldehyde-activating enzyme Provide feedback

The GFA enzyme catalyzes the first step in the detoxification of formaldehyde. This domain has a beta-tent fold [1].

InterPro entry IPR006913

Centrome protein (CENP)-V is a kinetochore protein that drives the progression of mitosis by coordinating chromatin condensation, positioning of sister chromatid centromeres and targeting of the chromosome passager complex (CPC), a machinery that regulates the attachment of spindle microtubules (MTs) to kinetochores. CENP-V homologues are found in all vertebrates as well as in plants and nematodes. At the C-terminal end, CENP-V possesses an evolutionally conserved domain that comprises an array of seven cysteines and shows high structural similarity to glutathione-dependent formaldehyde-activating enzyme (Gfa), an enzyme responsible for formaldehyde detoxification in prokaryotes. CENP-V could be an enzyme that scavenges the formaldehyde produced in histone demethylation reactions. The three central cysteines and the flanking four cysteines separately coordinate to zinc, forming a catalytic centre and a structural fold for a tertiary structure, respectively [ PUBMED:18772885 , PUBMED:19930468 , PUBMED:15548539 ].

The main topological feature of the CENP-V/GFA domain is an extremely twisted mixed eight-stranded beta-shee. Within this beta-sheet, the strands beta8, beta9, and beta4 form a sandwich with another triple stranded mixed beta-sheet (beta5, beta2, beta1). The interconnection between the sheets is mediated by four 3(10) helices and two alpha helices. The sandwich arrangement of the beta-strands is further buttressed by a terahedral zinc coordinated by the side chains of four cysteines. It appears that this zinc atom has only a structural role. A second zinc ion stabilizes a large hairpin loop that connects beta3 and beta4 via residues of three cysteines [ PUBMED:15548539 ].

This entry represents the CENP-V/GFA domain.

Pfam Clan

This family is a member of clan Beta-tent (CL0080), which has the following description:

This clan contains TCTP, Mss4 and SelR families [1]. The common fold of members of this superfamily has been termed the beta-tent fold [2]. This fold contains two four stranded antiparallel beta sheets. These are oriented at right angles and pinned together at their tip by a zinc ion [2].

The clan contains the following 7 members:

GFA Mss4 NTP_transf_9 RIG-I_C-RD SelR TCTP Yippee-Mis18


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 logo

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 GFA domain has been found. There are 16 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.
