1.21.3.6 | homology modeling using grenache polyphenol oxidase and sweet potato catechol oxidase as templates. The structure is folded into 15alpha-helices and 5 beta-sheets, and mostly composed by loops. The core of the enzyme is formed by a four-helix-bundle, and the helical bundle accommodates the dinuclear copper center. The cysteine residues Cys11, Cys25, Cys26, and Cys88 are highly conserved, and form disulfide bridges |
