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:
“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)
“... the structure of a page of good prose is, analyzed logically, not something frozen but the vibrating of a bridge, which changes with every step one takes on it.”
—Robert Musil (1880–1942)
“Vashtar: So it’s finished. A structure to house one man and the greatest treasure of all time.
Senta: And a structure that will last for all time.
Vashtar: Only history will tell that.
Senta: Sire, will he not be remembered?
Vashtar: Yes, he’ll be remembered. The pyramid’ll keep his memory alive. In that he built better than he knew.”
—William Faulkner (1897–1962)
