title: Amino acid sequence of Desulfovibrio vulgaris flavodoxin.
abstract: The complete amino acid sequence for the 148-amino acid flavodoxin from Desulfovibrio vulgaris was determined to be: H3N+-Met-Pro-Lys-Ala-Leu-Ile-Val-Tyr-Gly-Ser-Thr-Thr-Gly-Asn-Thr-Glu-Tyr-Thr-Ala-Glu-Thr-Ile-Ala-Arg-Glu-Leu-Ala-Asn-Ala-Gly-Tyr-Glu-Val-Asp-Ser-Arg-Asp-Ala-Ala-Ser-Val-Glu-Ala-Gly-Gly-Leu-Phe-Glu-Gly-Phe-Asp-Leu-Val-Leu-Leu-Gly-Cys-Ser-Thr-Trp-Gly-Asp-Asp-Ser-Ile-Glu-Leu-Gln-Asp-Asp-Phe-Ile-Pro-Leu-Phe-Asp-Ser-Leu-Glu-Glu-Thr-Gly-Ala-Gln-Gly-Arg-Lys-Val-Ala-Cys-Phe-Gly-Cys-Gly-Asp-Ser-Ser-Tyr-Glu-Tyr-Phe-Cys-Gly-Ala-Val-Asp-Ala-IleGlu-Glu-Lys-Leu-Lys-Asn-Leu-Gly-Ala-Glu-Ile-Val-Gln-Asp-Gly-Leu-Arg-Ile-Asp-Gly-Asp-Pro-Arg-Ala-Ala-Arg-Asp-Asp-Ile-Val-Gly-Try-Ala-His-Asp-Val-Arg-Gly-Ala-Ile-COO. This protein is of interest as it was the first flavoenzyme for which high resolution x-ray diffraction studies were published (Watenpaugh, K.D., Sieker, L.C., and Jensen, L.H. (1973) Proc. NAtl. Acad. Sci. U.S.A. 70, 3857-3860). Ser(10), Thr(12), Asn(14), and Thr(15) were shown to bind the phosphate of the FMN while the isoalloxazine ring is positioned between Trp(60) and Tyr(98).
