Summary: Probable N6-adenine methyltransferase
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.
Probable N6-adenine methyltransferase Provide feedback
This is a protein of approximately 200 residues which is conserved from plants to humans . It contains a highly conserved QFW motif close to the N-terminus and a DPPF motif in the centre. The DPPF motif is characteristic of N-6 adenine-specific DNA methylases, and this family is found in eukaryotes .

InterPro entry IPR019369
This family of proteins, which are of approximately 200 residues in length, contain a highly conserved Glu-Phe-Trp (QFW) motif close to the N terminus and an Asp/Asn-Pro-Pro-Tyr/Phe motif in the centre. This latter motif is characteristic of N-6 adenine-specific DNA methylases and could be involved in substrate binding or in the catalytic activity (PUBMED:7607512, PUBMED:16479578).

A class of redox enzymes are two domain proteins. One domain, termed the catalytic domain, confers substrate specificity and the precise reaction of the enzyme. The other domain, which is common to this class of redox enzymes, is a Rossmann-fold domain. The Rossmann domain binds nicotinamide adenine dinucleotide (NAD+) and it is this cofactor that reversibly accepts a hydride ion, which is lost or gained by the substrate in the redox reaction. Rossmann domains have an alpha/beta fold, which has a central beta sheet, with approximately five alpha helices found surrounding the beta sheet.The strands forming the beta sheet are found in the following characteristic order 654123. The inter sheet crossover of the stands in the sheet form the NAD+ binding site . In some more distantly relate Rossmann domains the NAD+ cofactor is replaced by the functionally similar cofactor FAD.

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request
