Summary: Putative heavy-metal-binding
Putative heavy-metal-binding Provide feedback
From comparative structural analysis, this family is likely to be a heavy-metal binding domain. The domain oligomerises as a pentamer. The domain is about 100 amino acids long and is found in prokaryotes.

This superfamily is characterised by chains that form pentamers. Family structures are beta/alpha-propellers with additional short beta-strands that promote oligomeric assembly. Family members appear to be heavy-metal binding proteins.
The clan contains the following 2 members:SeleniumBinding YbjQ_1
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 UniProtKB sequence database using the family HMM
- 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:

There is 1 interaction for this family. More...
We determine these interactions using iPfam, which considers the interactions between residues in three-dimensional protein structures and maps those interactions back to Pfam families. You can find more information about the iPfam algorithm in the journal article that accompanies the website.
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 YbjQ_1 domain has been found. There are 15 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 seqence.
