a selection of the results , presented here , indicates that ( i ) every archaebacterial ef-tu is closer ( immunochemically ) to every other archaebacterial ef-tu than to the functionally analogous proteins of eubacteria and eukaryotes , with only one possible exception concerning the recognition of eukaryotic ( ef-1 alpha ) factors by thermococcus ef-tu antibodies , and ( ii ) within the archaebacteria there appears to be a correlation between ef-tu immunochemical similarities and the phylogenetic relatedness of the organisms inferred from other ( sequence ) criteria .
