Clan: PFK (CL0240)


PFK-like superfamily Add an annotation

This clan includes two SCOP superfamilies. Strong similarities between NAD kinases, DAG kinase, sphingosine kinase and PFK have previously been shown[1].

This clan contains 3 families and the total number of domains in the clan is 76061. The clan was built by A Bateman.

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.
