Structure
There is no crystal structure available for sarcosine dehydrogenase. Sarcosine dehydrogenase contains a covalently bound FAD group " linked via the 8 alpha position of the isoalloxazine ring to an imidazole N(3) of a histidine residue". The enzyme, according to Freisell Wr. et al., also contains non-heme iron in a ratio of 1 or 2 iron per 300000g of enzyme, and 0.5 mol of acid soluble sulfur suggesting that the electron transfer during the first step in the reaction might proceed through a different pathway than that of Fe-S clusters.

Famous quotes containing the word structure:
“The question is still asked of women: “How do you propose to answer the need for child care?” That is an obvious attempt to structure conflict in the old terms. The questions are rather: “If we as a human community want children, how does the total society propose to provide for them?””
—Jean Baker Miller (20th century)
“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
“Agnosticism is a perfectly respectable and tenable philosophical position; it is not dogmatic and makes no pronouncements about the ultimate truths of the universe. It remains open to evidence and persuasion; lacking faith, it nevertheless does not deride faith. Atheism, on the other hand, is as unyielding and dogmatic about religious belief as true believers are about heathens. It tries to use reason to demolish a structure that is not built upon reason.”
—Sydney J. Harris (1917–1986)
