    The amino acid sequences of the flavin-peptides of dimethylglycine dehydrogenase and sarcosine dehydrogenase from rat liver mitochondria.

    Cook RJ, Misono KS, Wagner C.

    The flavoenzymes dimethylglycine dehydrogenase (EC 1.5.99.2) and sarcosine dehydrogenase (EC 1.5.99.1) contain covalently bound FAD linked via the 8 alpha-position of the isoalloxazine ring to the imidazole N(3) of a histidine residue (Cook, R. J., Misono, K. S., and Wagner, C. (1984) J. Biol. Chem. 259, 12475-12480). The flavin-peptides from tryptic digests of these two enzymes have been isolated and sequenced. Automated sequence analysis showed that the flavin-peptide from dimethylglycine dehydrogenase contained 25 amino acid residues in the following sequence: Ser-Glu-Leu-Thr-Ala-Gly-Ser- Thr-Trp-His(flavin)-Ala-Ala-Gly-Leu-Thr-Thr-Tyr-Phe-His-Pro-Gly-Ile-A sn-Leu-Lys. The sequence determined for the flavin-peptide from sarcosine dehydrogenase contained 14 amino acid residues Leu-Thr-Ser-Gly-Thr-Thr-Trp-His(flavin)-Thr-Ala-Gly-Leu-Gly-Arg.
