Clan: PFL-like (CL0339)


PFL-like glycyl radical enzyme superfamily Add an annotation

The N- and C-terminal halves of the structure have similar topologies but in some cases only one is represented by the members here, viz; the C-terminal domain of the R1 subunit of ribonucleotide reductase, and the N-terminal of PFL. The full-length structure is modelled by NRDD.

This clan contains 6 families and the total number of domains in the clan is 106640. The clan was built by P Coggill.


This clan contains the following 6 member families:

DUF3029 DUF711 Gly_radical NRDD PFL-like Ribonuc_red_lgC

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.
