SpeciesHomo sapiens (NCBI taxonomy ID: 9606)
GO0016021 integral to membrane (TAS)
Domain Architecture (Details)
InterPro domains unassigned to SynO:
Alcohol dehydrogenase () (ADH) catalyzes the reversible oxidation ofalcohols to their corresponding acetaldehyde or ketone with the concomitant reduction of NAD:alcohol + NAD = aldehyde or ketone + NADHCurrently three structurally and catalytically different types of alcoholdehydrogenases are known:Zinc-containing long-chain alcohol dehydrogenases.Insect-type.r short-chain alcohol dehydrogenases.Iron-containing alcohol dehydrogenases.Zinc-containing ADHs .re dimeric or tetrameric enzymes that bind twoatoms of zinc per subunit. One of the zinc atom is essential for catalyticactivity while the other is not. Both zinc atoms are coordinated by eithercysteine or histidine residues; the catalytic zinc is coordinated by twocysteines and one histidine. Zinc-containing ADHs are found in bacteria.ammals.lants.nd in fungi. In many species there is more than one isozyme(for example.umans have at least six isozymes.east have Anumber of other zinc-dependent dehydrogenases are closely related to zincADH and are included in this family.Sorbitol dehydrogenase ()L-threonine 3-dehydrogenase ()Glutathione-dependent formaldehyde dehydrogenase ()Mannitol dehydrogenase () In addition.his family includes NADP-dependent quinone oxidoreductase ().n enzyme found in bacteria (gene qor).n yeast and in mammals where.n somespecies such as rodents.t has been recruited as an eye lens protein and isknown as zeta-crystallin . The sequence of quinone oxidoreductase isdistantly related to that other zinc-containing alcohol dehydrogenases and itlacks the zinc-ligand residues. The torpedo fish and mammalian synaptic vesiclemembrane protein vat-1 is related to qor.This entry represents the cofactor-binding domain of these enzymes.hich is mornally found towards the C-terminus. Structural studies indicate that it forms a classical Rossman fold that reversibly binds NAD(H) .
  IPR013149:Alcohol dehydrogenase, zinc-binding
This is the catalytic domain of alcohol dehydrogenases. Many of them contain an inserted zinc binding domain. This domain has a GroES-like structure .
  IPR013154:Alcohol dehydrogenase GroES-like
GroES (chaperonin 10) is an oligomeric molecular chaperone.hich functions in protein folding and possibly in intercellular signalling.eing found on the surface of various prokaryotic and eukaryotic cells.s well as being released from cells. Secreted chaperonins are thought to act as intercellular signals.nteracting with a variety of cell types.ncluding leukocytes.ascular endothelial cells and epithelial cells.s well as activating key cellular activities such as the synthesis of cytokines and adhesion proteins . GroES works as a co-chaperone with GroEL (chaperonin 60) during protein folding. The polypeptide substrate is captured by GroEL.hich bind the co-chaperone GroES and ATP.nd discharges the substrate into a unique microenvironment inside of the chaperone.hich promotes productive folding. After hydrolysis of ATP.he polypeptide is released into solution . GP31 from bacteriophage T4 is functionally equivalent to GroES. GroES folds as a partly opened beta-barrel.The N-terminal domain of alcohol dehydrogenase-like proteins have a GroES-like fold.he C-terminal domain having a classical Rossman-fold . These proteins include.lcohol dehydrogenase.hich contains a zinc-finger subdomain within the GroES-like domain.etose reductase (sorbitol dehydrogenase).ormaldehyde dehydrogenase.uinone oxidoreductase and 2.-dienoyl-CoA reductase.The SSF signature in this entry is currently under review. Please be aware that some of the protein hits may be false positives.
