The invention relates to compositions and methods for the preparation, manufacture and therapeutic use of polynucleotides, primary transcripts and mmRNA molecules.

A microorganism is transformed to be capable of producing guanidinoacetic acid (GAA). A method can be used for the fermentative production of GAA using such a microorganism. A corresponding method can be used for the fermentative production of creatine.

The invention relates to compositions and methods for the preparation, manufacture and therapeutic use of polynucleotides, primary transcripts and mmRNA molecules.

A replication-competent recombinant virus includes an expression cassette encoding a protein associated with arginine biosynthesis. The protein associated with arginine biosynthesis may include argininosuccinate synthase 1 (ASS1), argininosuccinate lyase (ASL), or ornithine transcarboxylase (OTC). The recombinant virus may be derived from a myxoma virus. A method of treating a cell includes contacting a cell with a recombinant virus including an expression cassette encoding a protein associated with arginine biosynthesis. The protein associated with arginine biosynthesis may be ASS1, ASL, OTC.

The present invention relates to the provision of genetically modified microbial cells, such as yeast cells with an improved ability for producing L-ornithine and its derivatives. Overproduction of L-ornithine is obtained in the first place by the down-regulation or attenuation of specially selected genes, wherein said genes encode enzymes involved in the L-ornithine consumption and/or degradation pathways. Further L-ornithine production ability is improved by down-regulation, attenuation, deletion or overexpression of specially selected genes, wherein said genes encode enzymes and/or proteins involved in the L-ornithine acetylated derivatives cycle, L-glutamate synthesis pathways, subcellular trafficking, TCA cycle, pyruvate carboxylation pathway, respiratory electron-transport chain, and the carbon substrates' assimilation machinery. The invention additionally provides a method to produce L-ornithine with said modified eukaryotic cells.

This invention provides a range of translatable messenger UNA (mUNA) molecules. The mUNA molecules can be translated in vitro and in vivo to provide an active polypeptide or protein, or to provide an immunization agent or vaccine component. The mUNA molecules can be used as an active agent to express an active polypeptide or protein in cells or subjects. Among other things, the mUNA molecules are useful in methods for treating rare diseases.
