Powering down the Pfam website
On October 5th, we began redirecting traffic from Pfam (pfam.xfam.org) to InterPro (www.ebi.ac.uk/interpro). The Pfam website will remain available at pfam-legacy.xfam.org until January 2023, when it will be decommissioned. You can read more about the sunset period in our blog post.

Clan: AsmA-like (CL0401)


AsmA-like OmpF regulator protein superfamily Add an annotation

Families in this collection are AsmA-like. Mutations in the AsmA gene restore the assembly of OmpF, a trimeric outer membrane porin from E coli and related bacteria necessary for the cytotoxic action of group-A colicins.

This clan contains 7 families and the total number of domains in the clan is 20804. The clan was built by A Bateman.


This clan contains the following 7 member families:

AsmA AsmA_1 AsmA_2 DUF3971 DUF748 T2SSN TamB

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the MSD group, to allow us to map Pfam domains onto UniProt three-dimensional structures. The table below shows the mapping between the Pfam families in this clan, the corresponding UniProt entries, and the region of the three-dimensional structures that are available for that sequence.
