>gnl|CDD|58062 cd03709, lepA_C, lepA_C: This family represents the C-terminal region of LepA, a GTP-binding protein localized in the cytoplasmic membrane. LepA is ubiquitous in Bacteria and Eukaryota (e.g. Saccharomyces cerevisiae GUF1p), but is missing from Archaea. LepA exhibits significant homology to elongation factors (EFs) Tu and G. The function(s) of the proteins in this family are unknown. The N-terminal domain of LepA is homologous to a domain of similar size found in initiation factor 2 (IF2), and in EF-Tu and EF-G (factors required for translation in Escherichia coli). Two types of phylogenetic tree, rooted by other GTP-binding proteins, suggest that eukaryotic homologs (including S. cerevisiae GUF1) originated within the bacterial LepA family. LepA has never been observed in archaea, and eukaryl LepA is organellar. LepA is therefore a true bacterial GTPase, found only in the bacterial lineage.. Length = 80
