Nickel-dependent hydrogenase, large subunit, nickel binding site (IPR018194) Hydrogenases are enzymes that catalyze the reversible activation of hydrogen and which occur widely in prokaryotes as well as in some eukaryotes. There are various types of hydrog...

Transferrin family, iron binding site (IPR018195) Transferrins are a family of eukaryotic iron-binding glycoproteins that share the common function of controlling the level of free iron in biological fluids. The transferrin famil...

EF-Hand 1, calcium-binding site (IPR018247) Many calcium-binding proteins belong to the same evolutionary family and share a type of calcium-binding domain known as the EF-hand. This type of domain consists of a twelve resi...

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...

Hexokinase, binding site (IPR019807) Hexokinase (EC 2.7.1.1) is an important glycolytic enzyme that catalyses the phosphorylation of keto- and aldohexoses (e.g. glucose, mannose and fructose) using MgATP as the phosp...

Sigma-54 interaction domain, ATP-binding site 2 (IPR025943) Some bacterial regulatory proteins activate the expression of genes from promoters recognised by core RNA polymerase associated with the alternative sigma-54 factor. These have a ...

Haemerythrin, iron-binding site (IPR016131) The haemerythrin family is composed of haemerythrin proteins found in invertebrates, and a broader collection of bacterial and archaeal homologues. Haemerythrin is an oxygen-bindi...

ATP synthase, F0 complex, subunit C, DCCD-binding site (IPR020537) Transmembrane ATPases are membrane-bound enzyme complexes/ion transporters that use ATP hydrolysis to drive the transport of protons across a membrane. Some transmembrane ATPases ...

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...

Molybdopterin oxidoreductase, molybdopterin cofactor binding site (IPR027467) The molybdopterin oxidoreductase 4Fe-4S domain is found in a number of reductase/dehydrogenase families, which include the periplasmic nitrate reductase precursor and the formate ...
