Crystallization (Commentary)

Crystallization (Comment) Organism
crystal structure of the apoenzyme as well as its NADP+-bound state with resolutions down to 2.8 A. ADH displays a homotetrameric quaternary structure that can be described as a dimer of homodimers while in each subunit a seven-stranded parallel beta-sheet, flanked by three alpha-helices on each side, forms a Rossmann fold-type dinucleotide binding domain. NADP+ specificity is largely governed by the residues Asn15, Gly37, Arg38, and Arg39 Ralstonia sp.

Protein Variants
