... [24], we analyzed the effects of changing three lysine residues in TatA (residues 37, 40 and 41) to glutamine, and in a second mutant we addi-tionally changed K24 to alanine. These mutants,denoted ... B(2001) Membrane interactions and self association of the TatA and TatB components of the twin-argininetranslocation pathway. FEBS Letts 506, 143–148.32 Yohannan S, Yang D, Faham S, Boulting D, Whitel-egge ... cytoplasmicregions of TatA and TatB, and the highly conservedresidues of TatC have also been probed [24–27]. In thisreport we have analyzed the transmembrane regions of TatA and TatB, in an effort to analyze...
