CDC48_N | pfam02359 | Cell division protein 48 (CDC48), N-terminal domain. This domain has a double psi-beta barrel fold and includes VCP-like ATPase and N-ethylmaleimide sensitive fusion protein N-terminal domains. Both the VAT and NSF N-terminal functional domains consist of two structural domains of which this is at the N-terminus. The VAT-N domain found in AAA ATPases pfam00004 is a substrate 185-residue recognition domain. | FtsH_ext | pfam06480 | FtsH Extracellular. This domain is found in the FtsH family of proteins. FtsH is the only membrane-bound ATP-dependent protease universally conserved in prokaryotes. It only efficiently degrades proteins that have a low thermodynamic stability - e.g. it lacks robust unfoldase activity. This feature may be key and implies that this could be a criterion for degrading a protein. In Oenococcus oeni FtsH is involved in protection against environmental stress, and shows increased expression under heat or osmotic stress. These two lines of evidence suggest that it is a fundamental prokaryotic self-protection mechanism that checks if proteins are correctly folded (personal obs: Yeats C). The precise function of this N-terminal region is unclear. | Peptidase_M41 | pfam01434 | Peptidase family M41. | Rep_fac_C | pfam08542 | Replication factor C C-terminal domain. This is the C-terminal domain of RFC (replication factor-C) protein of the clamp loader complex which binds to the DNA sliding clamp (proliferating cell nuclear antigen, PCNA). The five modules of RFC assemble into a right-handed spiral, which results in only three of the five RFC subunits (RFC-A, RFC-B and RFC-C) making contact with PCNA, leaving a wedge-shaped gap between RFC-E and the PCNA clamp-loader complex. The C-terminal is vital for the correct orientation of RFC-E with respect to RFC-A. | Vps4_C | pfam09336 | Vps4 C terminal oligomerisation domain. This domain is found at the C terminal of ATPase proteins involved in vacuolar sorting. It forms an alpha helix structure and is required for oligomerisation. | Lon_C | pfam05362 | Lon protease (S16) C-terminal proteolytic domain. The Lon serine proteases must hydrolyse ATP to degrade protein substrates. In Escherichia coli, these proteases are involved in turnover of intracellular proteins, including abnormal proteins following heat-shock. The active site for protease activity resides in a C-terminal domain. The Lon proteases are classified as family S16 in Merops. |
