  • Title: Cloning and sequencing of the inulinase gene of Kluyveromyces marxianus var. marxianus ATCC 12424.
    Author: Laloux O, Cassart JP, Delcour J, Van Beeumen J, Vandenhaute J.
    Journal: FEBS Lett; 1991 Sep 02; 289(1):64-8. PubMed ID: 1840529.
    Abstract:
    Cell wall inulinase (EC 3.2.1.7) was purified from Kluyveromyces marxianus var. marxianus (formerly K. fragilis) and its N-terminal 33-amino acid sequence was established. PCR amplification of cDNA with 2 sets of degenerate primers yielded a genomic probe which was then used to screen a genomic library established in the YEp351 yeast shuttle vector. One of the selected recombinant plasmids allowed an invertase-negative Saccharomyces cerevisiae mutant to grow on inulin. It was shown to contain an inulinase gene (INU 1) encoding a 555-amino acid precursor protein with a typical N-terminal signal peptide. The sequence of inulinase displays a high similarity (67%) to S. cerevisiae invertase, suggesting a common evolutionary origin for yeast beta-fructosidases with different substrate preferences.
