Saccharomyces cerevisiae invertase (ScInv) is an enzyme encoded by the SUC2 gene that releases β-fructose from the nonreducing termini of various β-D-fructofuranoside substrates. Its ability to produce 6-kestose by transglycosylation makes this enzyme an interesting research target for applications in industrial biotechnology. The native enzyme, which presents a high degree of oligomerization, was crystallized by vapour-diffusion methods. The crystals belonged to space group P3121, with unit-cell parameters a = 268.6, b = 268.6, c = 224.4 Å. The crystals diffracted to 3.3 Å resolution and gave complete data sets using a synchrotron X-ray source.
