Abstract: The present disclosure relates to a genetically modified cell capable of utilizing sucrose as energy and carbon source following the expression of a single heterologous enzyme, which upon expression is translocated from the cytosol and which is capable of hydrolysing non-phosphorylated sucrose into fructose and glucose.The identification of efficient enzymes capable of hydrolysing sucrose in its non-modified form, and which on its own enable the cell to utilize sucrose as a, or as the main and/or sole, carbon and/or energy source, i.e., without the need for multi-gene sucrose utilizing systems comprising several other heterologous polypeptides, such as other enzymes and/or transporters, is highly advantageous, since it allows for cost-effective use of sucrose in large scale production processes.

Abstract: A genetically modified yeast cell, wherein the yeast cell comprises a genetic modification comprising overexpression of yeast gene encoding porphobilinogen deaminase (HEM3), the HEM3 gene having at least 80 % identity with SEQ ID No. 7. The genome of the modified yeast cell further comprises one or more genetic modifications in one or more genes selected from: genes coding for heme-dependent repressor of hypoxic genes (ROX1), genes coding for heme oxygenase (HMX1), genes coding for a receptor for vacuolar proteases (VPS10), and genes coding for vacuolar proteinase (PEP4), the one or more genetic modifications being such that expression of a polypeptide from such a gene is reduced or disrupted or the polypeptide expressed is non-functional.
