Clan: HotDog (CL0050)

Summary

HotDog superfamily Add an annotation

The HotDog fold was first observed in the structure of Escherichia coli beta-hydroxydecanoyl thiol ester dehydratase (FabA), where Leesong et al. noticed that each subunit of this dimeric enzyme contained a mixed alpha + beta 'hot dog' fold. They described the seven-stranded antiparallel beta-sheet as the 'bun', which wraps around a five-turn alpha-helical 'sausage', This superfamily contains a diverse range of enzymes. Membership includes numerous prokaryotic, archaeal and eukaryotic proteins involved in several related, but distinct, catalytic activities, from metabolic roles such as thioester hydrolysis in fatty acid metabolism, to degradation of phenylacetic acid and the environmental pollutant 4-chlorobenzoate. The superfamily also includes FapR, a non-catalytic bacterial homologue that is involved in transcriptional regulation of fatty acid biosynthesis [1].

This clan contains 13 families and the total number of domains in the clan is 52323. The clan was built by A Bateman.

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 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.
