Clan: YjbJ-CsbD-like (CL0406)


YjbJ-CsbD-like superfamily Add an annotation

CsbD is a bacterial general stress response protein. It's expression is mediated by sigma-B, an alternative sigma factor [1]. The role of CsbD in stress response is unclear. YjbJ is a hypothetical protein with a similar structure.

This clan contains 2 families and the total number of domains in the clan is 7615. The clan was built by RD Finn.

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.
