== Publication Abstract from PubMed ==

Glycine decarboxylase consists of four protein components. Its structural and mechanistic heart is provided by the lipoic acid-containing H-protein which undergoes a cycle of reductive methylamination, methylamine transfer and electron transfer. Lipoic acid attached to a specific lysine side chain is assumed to act as a 'swinging arm' conveying the reactive dithiolane ring from one catalytic centre to another. The X-ray crystal structures of two forms of the H-protein have been determined. The lipoate cofactor is located in the loop of a hairpin configuration but following methylamine transfer it is pivoted to bind into a cleft at the surface of the H-protein. The lipoamide-methylamine arm is, therefore, not free to move in aqueous solvent.

The lipoamide arm in the glycine decarboxylase complex is not freely swinging.,Cohen-Addad C, Pares S, Sieker L, Neuburger M, Douce R Nat Struct Biol. 1995 Jan;2(1):63-8. PMID:7719855<ref>PMID:7719855</ref>
