Translation elongation factor EF1A/initiation factor IF2gamma, C-terminal
IPR009001
Definition
A β barrel of circularly permuted topology is found in the C terminus of many translation elongation and initiation factors. This domain is found in the elongation factors EF1A (or EF-Tu) of both eukaryotes and prokaryotes, which functions to recognise and transport aminoacyl-tRNA to the acceptor (A) site of the ribosome during the elongation process [[cite:PMID:10715211], [cite:PMID:11106763]]. This domain is also found in the initiation factor IF2 gamma subunit of eukaryotes PMID:11927566, which functions to transport the initiator methionyl-tRNA to the ribosome. The C-terminal extension of mitochondrial EF1A (or EF-Tu) has structural similarities with DNA recognising zinc fingers, suggesting that the extension may be involved in recognition of RNA.
