EXAMPLE

Supra-domain in Translation Factors: the "P-loop containing nucleotide trphosphate hydrolases" domain and the "Translation proteins" domain. This supra-domain occurs in prokaryotic and eukaryotic translation factors that hydrolyse GTP. GTP hydrolysis in the P-loop domain drives the conformational change in the Translation proteins domain, which is then transmitted onto the ribosome. The supra-domain occurs in 35 different domain architectures, and five of these are given here. The inset shows a protein of known structure, which contains the supra-domain (PDB: 1jny) (Vitagliano et al., 2001)
