Fig 6. The Nad7 Leu²⁶ (L²⁶) and Atp1 Leu⁴³¹ (L⁴³¹) residues are highly conserved, while the residue at Atp8-146 are variable.

(A-C) Alignment of the neighboring gDNA sequences of nad7, atp1 and atp8. The nucleotide sequences and cDNA sequences were derived from GenBank/EST and GenBank/EMBL databases. The sites at which editing is abolished in the emp21 mutant are arrowed.
