In certain embodiments, the present disclosure provides compositions and methods for treating Forbes-Cori Disease.

A process for the production of ethanol. comprising: fermentation of a feed. under anaerobic conditions. wherein the feed contains a di-saccharide. oligo-saccharide and/or poly-saccharide and wherein the fermentation is carried out in the presence of a recombinant yeast cell. which recombinant yeast produces a combination of proteins having glucosidase activity: and recovery of ethanol. and a recombinant yeast cell for use therein.

An immune cell that is genetically engineered to express an exogenous alternative carbon source (ACS) metabolism gene, in which the ACS is not glucose and wherein the ability of the immune cell to metabolise the ACS is increased due to expression of the exogenous ACS metabolism gene. Also provided are polynucleotides, vectors, pharmaceutical compositions, methods of genetically engineering the immune cell and methods of use in therapy.

The present invention relates to isolated polypeptides having alpha-glucuronidase activity, catalytic domains and polynucleotides encoding the polypeptides, catalytic domains. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides or catalytic domains.

Disclosed are recombinant mutant isomaltase enzymes, and pharmaceutical compositions comprising an isomaltase enzyme, e.g., a recombinant mutant isomaltase enzyme, and an optional invertase enzyme. The enzymes and compositions can be used, among other things, to treat congenital sucrase-isomaltase deficiency (CSID).
