Figure 4.

Comparison between the N-terminal sequences of NdhA, NdhH, and NdhK subunits (Fig. 3C) of purified pea Ndh complex and sequences predicted from the plastid genome of other plants. The sequences of the ndh genes from pea are not known; therefore, the N-terminal data for pea (Pisum sativum) is compared with the predicted sequences of the NdhA, NdhH, and NdhK proteins from tobacco (Nicotiana tabacum) (1) and yellow lupine (Lupinus luteus) (Swiss Prot accession no. P52766). Asterisks, identical residues; dots, conservative changes. Numbers indicate position of the residue from the N terminus.
