InterPro entry IPR000182

The N-acetyltransferases (NAT) (EC 2.3.1.-) are enzymes that use acetyl coenzyme A (CoA) to transfer an acetyl group to a substrate, a reaction implicated in various functions from bacterial antibiotic resistance to mammalian circadian rhythm and chromatin remodeling. The Gcn5-related N-acetyltransferases (GNAT) catalyze the transfer of the acetyl from the CoA donor to a primary amine of the acceptor. The GNAT proteins share a domain composed of four conserved sequence motifs A-D [ PUBMED:9175471 , PUBMED:10940244 ]. This GNAT domain is named after yeast GCN5 (from General Control Nonrepressed) and related histone acetyltransferases (HATs) like Hat1 and PCAF. HATs acetylate lysine residues of N-terminal histone tails, resulting in transcription activation. Another category of GNAT, the aminoglycoside N-acetyltransferases, confer antibiotic resistance by catalyzing the acetylation of amino groups in aminoglycoside antibiotics [ PUBMED:12592013 ]. GNAT proteins can also have anabolic and catabolic functions in both prokaryotes and eukaryotes [ PUBMED:9175471 , PUBMED:10940244 , PUBMED:12592013 , PUBMED:12527305 , PUBMED:15581578 ].

The acetyltransferase/GNAT domain forms a structurally conserved fold of 6 to 7 beta strands (B) and 4 helices (H) in the topology B1-H1-H2-B2-B3-B4-H3-B5-H4-B6, followed by a C-terminal strand which may be from the same monomer or contributed by another [ PUBMED:10940244 , PUBMED:15581578 ]. Motifs D (B2-B3), A (B4-H3) and B (B5-H4) are collectively called the HAT core [ PUBMED:10940244 , PUBMED:12527305 , PUBMED:15581578 ], while the N-terminal motif C (B1-H1) is less conserved.

Some proteins known to contain a GNAT domain:

  • Yeast GCN5 and Hat1, which are histone acetyltransferases (EC 2.3.1.48).
  • Human PCAF, a histone acetyltransferase.
  • Mammalian serotonin N-acetyltransferase (SNAT) or arylalkylamine NAT (AANAT), which acetylates serotonin into a circadian neurohormone that may participate in light-dark rhythms, and human mood and behavior.
  • Mammalian glucosamine 6-phosphate N-acetyltransferase (GNA1) (EC 2.3.1.4).
  • Escherichia coli rimI and rimJ, which acetylate the N-terminal alanine of ribosomal proteins S18 and S5, respectively (EC 2.3.1.128).
  • Mycobacterium tuberculosis aminoglycoside 2'-N-acetyltransferase (aac), which acetylates the 2' hydroxyl or amino group of a broad spectrum of aminoglycoside antibiotics.
  • Bacillus subtilis bltD and paiA, which acetylate spermine and spermidine.

Alignments

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...

Trees

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.

Structures

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 Acetyltransf_10 domain has been found. There are 51 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.
