6490627-10 1984 Amino acid composition and N-terminal analysis suggested the sequence of the flavin-peptide of sarcosine dehydrogenase was His(flavin)-(Ala, Gly,Thr)-Leu. 4,6-dinitro-o-cresol 77-83 sarcosine dehydrogenase Rattus norvegicus 95-118 6490600-3 1984 The 13C signals of 13C-enriched riboflavin or 3-methylriboflavin bound to RBP are broader than those of the free form, reflecting the

cells of anaemic animals and that these mechanisms vary among different species of animals. 4,6-dinitro-o-cresol 88-94 glutathione-disulfide reductase Bos taurus 64-66 6304088-6 1983 Since reduction of cytochrome c by L-lactate requires the catalytic action of flavocytochrome b2, it is concluded that the structure of the crystalline enzyme not only allows for electron transfer from L-lactate to flavin and intramolecular electron transfer from flavin to heme, but also for the formation of a productive complex with cytochrome c. 4,6-dinitro-o-cresol 215-221 cytochrome c, somatic Homo sapiens
