Fructofuranosidase from Rhodotorula dairenensis, molecular model. The image shows a ribbon rendition of fructofuranosidase with its homo 2-mer structure (green, red). The two small spacefilled molecules in the centre right are beta-D-mannopyranose-(1-4)-2-acetamido-2-deoxy-beta-D-glucopyranose-(1-4)-2-acetamido-2-deoxy-beta-D-glucopyranose. The two small molecules in the centre left are 2-acetamido-2-deoxy-beta-D-glucopyranose-(1-4)-2-acetamido-2-deoxy-beta-D-glucopyranose.
