ABC transporter transmembrane domain is main transmembrane structural unit of ATP-binding cassette transporter which consist of six transmembrane domaines. Many members of the ABC transporter family (Pfam PF00005) have two such regions.[1][2][3][4][5][6]

Pfam Clan

This family is a member of clan ABC_membrane (CL0241), which has the following description:

This clan includes families that are the membrane components of ABC transporter complexes. In general these regions are composed of six transmembrane helices [1].

The clan contains the following 4 members:

ABC_membrane ABC_membrane_2 ABC_membrane_3 SbmA_BacA

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 using the family HMM. We also generate alignments using four representative proteomes (RP) sets, the NCBI sequence database, and our metagenomics 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.

MyHits provides a collection of tools to handle multiple sequence alignments. For example, one can refine a seed alignment (sequence addition or removal, re-alignment or manual edition) and then search databases for remote homologs using HMMER3.

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...

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.
