| Abstract: | The N-terminal amino acid sequence of the 20 kDa (delta') subunit of the turnip (Brassica napus L.) mitochondrial F1-ATPase has been determined. Comparison of the sequence obtained with those of the epsilon subunits of chloroplast CF1, E. coli F1 and the delta subunit of bovine F1 shows that the turnip delta' subunit is another member of this family of homologous proteins. The delta' subunit of sweet potato F1-ATPase [(1989) J. Biol. Chem. 264, 3183-3186] is very similar to the turnip sequence and thus can also be considered to belong to this family. |
