Iron-containing alcohol dehydrogenases signatures


Alcohol dehydrogenase (EC (ADH) catalyzes the reversible oxidation of ethanol to acetaldehyde with the concomitant reduction of NAD [1]. Currently three, structurally and catalytically, different types of alcohol dehydrogenases are known:

  • Zinc-containing 'long-chain' alcohol dehydrogenases.
  • Insect-type, or 'short-chain' alcohol dehydrogenases.
  • Iron-containing alcohol dehydrogenases.

Iron-containing ADH's have been found in yeast (gene ADH4) [2], as well as in Zymomonas mobilis (gene adhB) [3]. These two iron-containing ADH's are closely related to the following enzymes:

  • Escherichia coli propanediol oxidoreductase (EC (gene fucO) [4], an enzyme involved in the metabolism of fucose and which also seems to contain ferrous ion(s).
  • Clostridium acetobutylicum NADPH- and NADH-dependent butanol dehydrogenases (EC 1.1.1.-) (genes adh1, bdhA and bdhB) [5], an enzyme which has activity using butanol and ethanol as substrates.
  • Escherichia coli adhE [6], an iron-dependent enzyme which harbor three different activities: alcohol dehydrogenase, acetaldehyde dehydrogenase (acetylating) (EC and pyruvate-formate-lyase deactivase.
  • Bacterial glycerol dehydrogenase (EC (gene gldA or dhaD) [7].
  • Clostridium kluyveri NAD-dependent 4-hydroxybutyrate dehydrogenase (4hbd) (EC
  • Citrobacter freundii and Klebsiella pneumoniae 1,3-propanediol dehydrogenase (EC (gene dhaT).
  • Bacillus methanolicus NAD-dependent methanol dehydrogenase (EC [8].
  • Escherichia coli and Salmonella typhimurium ethanolamine utilization protein eutG.
  • Escherichia coli hypothetical protein yiaY.
  • Escherichia coli hypothetical protein ybdH.
  • Escherichia coli hypothetical protein yqhD.
  • Methanococcus jannaschii hypothetical protein MJ0712.

The patterns that we developed to detect this class of enzymes are based on two conserved regions.
