Urease nickel binding site (IPR029754) Urease (urea amidohydrolase) is a nickel-binding enzyme that catalyses the hydrolysis of urea to carbon dioxide and ammonia. Historically, it was the first enzyme to be crystalliz...

Peptidase M16, zinc-binding site (IPR001431) Over 70 metallopeptidase families have been identified to date. In these enzymes a divalent cation which is usually zinc, but may be cobalt, manganese or copper, activates the wat...

Nitrite/sulphite reductase iron-sulphur/sirohaem-binding site (IPR006066) Nitrite reductases and bacterial sulphite reductases catalyse the 6-electron reduction of nitrite (sulphite) to ammonia (sulphide). On the basis of physiological function, 2 types...

Biotin-binding site (IPR001882) Biotin, which plays a catalytic role in some carboxyl transfer reactions, is covalently attached, via an amide bond, to a lysine residue in enzymes requiring this coenzyme. Sequen...

Multicopper oxidase, copper-binding site (IPR002355) The entry represents a conserved region containing the Cu-binding site found in multicopper oxidases. Multicopper oxidases oxidise their substrate by accepting electrons at a mono...

Copper centre Cu(A) (IPR001505) The Cu(A) centre contains a mixed valence binuclear copper binding site formed of about 50 amino acids containing two cysteines and histidines and one glutamate and methionine. Th...

Oxygen oxidoreductase covalent FAD-binding site (IPR006093) Some oxygen-dependent oxidoreductases are flavoproteins that contains a covalently bound FAD group which is attached to a histidine via an 8-alpha- (N3-histidyl)-riboflavin linkag...

Aminotransferase, class-II, pyridoxal-phosphate binding site (IPR001917) Aminotransferases share certain mechanistic features with other pyridoxal-phosphate dependent enzymes, such as the covalent binding of the pyridoxal-phosphate group to a lysine re...

Visual pigments (opsins) retinal binding site (IPR027430) Visual pigments are the light-absorbing molecules that mediate vision. They consist of an apoprotein, opsin, covalently linked to the chromophore cis-retinal. Vision is effected t...

Aconitase family, 4Fe-4S cluster binding site (IPR018136) Aconitase (aconitate hydratase) is the enzyme from the tricarboxylic acid cycle that catalyzes the reversible isomerization of citrate and isocitrate. Cis-aconitate is formed as a...
