Non-heme Iron Proteins

Abstract

Abstract The complete amino acid sequence of ferredoxin from the leaves of Leucaena glauca, a species of small leguminous tree, has been determined. This single polypeptide chain was found to contain 96 amino acid residues arranged as follows, with sequence heterogeneity occurring in positions 6, 12, 33, and 96: Ala-Phe-Lys-Val-Lys-Leua/Valb-Leu-Thr-Pro-Asp-Gly-Proa/Alab-Lys-Glu-Phe-Glu-Cys-Pro-Asp-Asp-Val-Tyr-Ile-Leu-Asp-Gln-Ala-Glu-Glu-Leu-Gly-Ile-Glux/Aspx-Leu-Pro-Tyr-Ser-Cys-Arg-Ala-Gly-Ser-Cys-Ser-Ser-Cys-Ala-Gly-Lys-Leu-Val-Glu-Gly-Asp-Leu-Asp-Gln-Ser-Asp-Gln-Ser-Phe-Leu-Asp-Asp-Glu-Gln-Ile-Glu-Glu-Gly-Trp-Val-Leu-Thr-Cys-Ala-Ala-Tyr-Pro-Arg-Ser-Asp-Val-Val-Ile-Glu-Thr-His-Lys-Glu-Glu-Glu-Leu-Thr-Glyx/Alax.
