dimension to the relationships suggested by sequence similarities. The structures reveal the …

GALACTOSE oxidase is an extracellular enzyme secreted by the fungus Dactylium
dendroides. It is monomeric, with a relative molecular mass of 68,000, catalyses the …

An active site, cofactor-containing peptide has been obtained in high yield from bovine
serum amine oxidase. Sequencing of this pentapeptide indicates: Leu-Asn-X-Asp-Tyr …

The N-terminal≈ 440 aa of integrin α subunits contain seven sequence repeats. These are
predicted here to fold into a β-propeller domain. A homologous domain from the enzyme …

Cation-π bonds and amino-aromatic interactions are known to be important contributors to
protein architecture and stability, and their role in ligand-protein interactions has also been …

Cytochrome cd1-nitrite reductase is a bifunctional enzyme that catalyzes the one-electron
reduction of nitrite to nitric oxide and the four-electron reduction of oxygen to water. The 1.55 …

Although quinones have been recognized as important electron-transfer agents in biology,
they have not been viewed as important redox cofactors. As we describe in this chapter, the …
