A method of producing collagen in a plant and plants producing collagen are provided. The method is effected by expressing in the plant at least one type of a collagen alpha chain in a manner enabling accumulation of the collagen alpha chain in a subcellular compartment devoid of endogenous P4H activity, thereby producing the collagen in the plant.

Wound healing is a complex homeostatic process in which several distinct types coordinate to repair a physical damage. Failure to close wounds contributes to the pathology of conditions like diabetes mellitus, particularly in the elderly. Presented herein are molecules, pharmaceutical compositions, and methods for applying small RNA oligonucleotide technology to wound healing. Small RNA oligonucleotide approaches as disclosed herein provide a therapeutic strategy for improving both basal and pathological wound healing.

Methods and compositions are described for enhancing tissue regeneration or wound repair in a mammalian subject comprising a composition comprising (a) a proline hydroxylase inhibitor component or molecule that increases or upregulates HIF1a and (b) a carrier component comprising a hydrogel.

A protein having an L-proline efflux function and the use thereof are provided. A method for producing L-proline or hydroxyproline by means of using a protein ThrE is used for producing L-proline by means of enhancing the activity of a polypeptide, having an L-proline efflux function, in an L-proline-producing strain. Alternatively, the method is used for producing hydroxyproline by means of weakening the activity of a polypeptide, having an L-proline efflux function, in L-proline-producing host cells and enhancing the activity of a proline hydroxylase.

The present invention aims to provide a mutant L-pipecolic acid hydroxylase for highly productive and highly selective production of cis-5-hydroxy-L-pipecolic acid by hydroxylation of L-pipecolic acid, and to provide a novel method for industrially producing cis-5-hydroxy-L-pipecolic acid from L-pipecolic acid with high productivity at low cost. The present invention provides a mutant L-pipecolic acid hydroxylase having an amino acid sequence that a particular amino acid mutation(s) is/are introduced in the amino acid sequence of SEQ ID NO:2.

The present disclosure provides engineered proline hydroxylase polypeptides for the production of hydroxylated compounds, polynucleotides encoding the engineered proline hydroxylases, host cells capable of expressing the engineered proline hydroxylases, and methods of using the engineered proline hydroxylases to prepare compounds useful in the production of active pharmaceutical agents.

A gene therapy DNA vector based on the VTvaf17 gene therapy DNA vector carrying a target gene selected from the group of genes COL1A1, COL1A2, P4HA1, P4HA2, COL7A1, CLCA2, ELN, PLOD1 to increase the expression level of this target gene in humans and animals. Moreover, the gene therapy DNA vector VTvaf17-COL1A1 or VTvaf17-COL1A2 or VTvaf17-P4HA1 or VTvaf17-P4HA2 or VTvaf17-COL7A1 or VTvaf17-CLCA2 or VTvaf17-ELN or VTvaf17-PLOD1 has the nucleotide sequence SEQ ID NO. SEQ ID No. 3 or SEQ ID No. 4 or SEQ ID No. 5 or SEQ ID No. 6 or SEQ ID No. 7 or SEQ ID No. 8, respectively. The DNA vector contains no nucleotide sequences of viral origin and no antibiotic resistance genes, providing the possibility of its safe use for genetic therapy in humans and animals.

The present disclosure provides engineered proline hydroxylase polypeptides for the production of hydroxylated compounds, polynucleotides encoding the engineered proline hydroxylases, host cells capable of expressing the engineered proline hydroxylases, and methods of using the engineered proline hydroxylases to prepare compounds useful in the production of active pharmaceutical agents.

This invention relates to genetically engineered strains of yeast and methods for producing recombinant protein (e.g., collagen). Recombinant protein of the present invention is used to produce biofabricated leather or a material having leather-like properties containing recombinant or engineered collagen. The yeast strains are engineered to produce ascorbate and/or increased production of ketoglutarate.
