A structural model was established for the N-terminal part of translation factor SelB which shares sequence similarity with EF-Tu, taking into account the coordinates of the EF-Tu 3D structure and the consensus of SelB sequences from four bacteria. The model showed that SelB is homologous in its N-terminal domains over all three domains of EF-Tu. The guanine nucleotide binding site and the residues involved in GTP hydrolysis are similar to those of EF-Tu, but with some subtle differences… CONTINUE READING
