Structural and biochemical characterization of Arabidopsis alcohol dehydrogenases reveals distinct functional properties but similar redox sensitivity.

Alcohol dehydrogenases (ADHs) are a group of zinc-binding enzymes belonging to the medium-length dehydrogenase/reductase (MDR) protein superfamily. In plants, these enzymes fulfill important functions involving the reduction of toxic aldehydes to the corresponding alcohols (as well as catalyzing the reverse reaction, i.e., alcohol oxidation; ADH1) and the reduction of nitrosoglutathione (GSNO; ADH2/GSNOR). We investigated and compared the structural and biochemical properties of ADH1 and GSNOR from Arabidopsis thaliana. We expressed and purified ADH1 and GSNOR and determined two new structures, NADH-ADH1 and apo-GSNOR, thus completing the structural landscape of Arabidopsis ADHs in both apo- and holo-forms. A structural comparison of these Arabidopsis ADHs revealed a high sequence conservation (59% identity) and a similar fold. In contrast, a striking dissimilarity was observed in the catalytic cavity supporting substrate specificity and accommodation. Consistently, ADH1 and GSNOR showed strict specificity for their substrates (ethanol and GSNO, respectively), although both enzymes had the ability to oxidize long-chain alcohols, with ADH1 performing better than GSNOR. Both enzymes contain a high number of cysteines (12 and 15 out of 379 residues for ADH1 and GSNOR, respectively) and showed a significant and similar responsivity to thiol-oxidizing agents, indicating that redox modifications may constitute a mechanism for controlling enzyme activity under both optimal growth and stress conditions. << Less

An NAD+-dependent alcohol dehydrogenase (ADH) of the Antarctic psychrophile Moraxella sp. TAE123 was purified to homogeneity with an overall yield of 16.7% and further characterized. The native enzyme had an apparent molecular mass of 240 kDa and consisted of four identical 52-kDa subunits. The pI of the enzyme was determined to be 5.5, while its optimum pH is 7.5. The enzyme contained 1 zinc atom/subunit and exhibited a remarkable thermal lability. Moraxella sp. TAE123 ADH exhibited a wide range of substrate specificity similar to its mammalian counterparts and in contrast to other microbial ADHs. It oxidized mainly primary and secondary aliphatic alcohols. The highest reaction rate was observed when ethanol was used as substrate. A gradual decrease in rate was observed by increasing the length and branching of the carbon chain of the alcohol. This enzyme oxidized effectively large bulky alcohols, such as diphenylmethanol. Reduction of aldehydes and ketones was also observed. N-terminal amino acid sequence analysis of the enzyme did not reveal any similarity with the amino termini of all other ADHs, while an unexpected significant similarity was observed with the amino terminal sequence of four prokaryotic aldehyde dehydrogenases. << Less
