EFG_C

EFG_C
PFAM accession number:PF00679
Interpro abstract (IPR000640):

Elongation factor 2 (EF2 or EFG) is folded into five domains, with domains I and II forming the N-terminal block, domains IV and V forming the C-terminal block, and domain III providing the covalently-linked flexible connection between the two [(PUBMED:11054294)]. This entry represents the domain V of EF2 of both prokaryotes and eukaryotes (also known as eEF2). This domain is also found in elongation factor 4 and some tetracycline resistance proteins and adopts a ferredoxin-like fold [(PUBMED:12471894)].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry EFG_C
