<p>LepA (GUF1 in Saccaromyces) is a GTP-binding membrane protein related to EF-G and EF-Tu. Two types of phylogenetic tree, rooted by other GTP-binding proteins, suggest that eukaryotic homologs (including GUF1 of yeast) originated within the bacterial LepA family. The function of the proteins in this family is unknown. </p><p>This entry represents the C-terminal region of these proteins [<cite idref="PUB00007679"/>].</p> GTP-binding protein LepA, C-terminal
