摘要：The complete amino acid sequence of [2Fe-2S] ferredoxin from Panax ginseng (Araliaceae) has been determined by automated Edman degradation of the entire S -carboxymethylcysteinyl protein and of the peptides obtained by enzymatic digestion. This ferredoxin has a unique amino acid sequence, which includes an insertion of Tyr at the 3rd position from the amino-terminus and a deletion of two amino acid residues at the carboxyl terminus. This ferredoxin had 18 differences in its amino acid sequence compared to that of Petroselinum sativum (Umbelliferae). In contrast, 23—33 differences were observed compared to other dicotyledonous plants. This suggests that Panax ginseng is related taxonomically to umbelliferous plants.
