The present disclosure provides production systems and host cells to produce collagen 7 compositions comprising recombinant collagen 7 and/or functional variants thereof. The host cells are genetically engineered to stably express rCol7 and functional variants thereof. The collagen 7 composition can be used to restore collagen 7 levels in a subject in need, and for preventing, preventing the progression of, alleviating, and delaying the on-set of a skin condition, e.g., skin wound associated with dystrophic epidermolysis bullosa (DEB).

The present invention 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.

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.

Provided are a proline hydroxylase and uses thereof. The proline hydroxylase comprises having the amino acid sequence of SEQ ID NO: 2 with the exception of a mutation of one or more amino acids; wherein the mutation of one or more amino acids must comprises E27K, and the mutation of one or more amino acids selected from the group consisting of: H14R, L16N, T25R, F26L, E27K, D30S, S33N, E34N, E34G, E34L, E34S, E34D, Y35W, Y35K, S37W, S37F, S37E, S37N, S37T, S37C, W40F, K41E, D54G, H55Q, S57L, I58T, I58Y, I58A, I58R, I58V, I58S, I58C, K86P, T91A, F95Y, C97Y, I98V, K106V, K106T, K106Q, F111S, K112E, K112R, S154A, K162E, L166M, I118F, I118V, I118R, H119R, H119F, I120V, K123D, K123N, K123Q, K123S, K123I, K123T, T130N, D134G, V135K, N165H, D173G, K209R, I223V and S225A, and having proline hydroxylase activity.

Light-generating fusion proteins having a ligand binding site and a light-generating polypeptide moiety and their use as diagnostics, in drug screening and discovery, and as therapeutics, are disclosed. The light-generating fusion protein has a feature where the bioluminescence of the polypeptide moiety changes upon binding of a ligand at the ligand binding site. The ligand may be, for example, an enzyme present in an environment only under certain conditions, e.g., ubiquitin ligase in a hypoxic state, such that the light-generating fusion protein is “turned on” only under such conditions.

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.

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 α ketoglutarate.

The disclosure herein provides a fusion protein comprising prolyl 4-hydroxylase alpha subunit (P4HA) and a soluble protein partner. A fusion protein comprising prolyl 4-hydroxylase alpha subunit (P4HA1) and prolyl 4-hydroxylase beta subunit (P4HB) is provided. A microorganism including a fusion protein comprising prolyl 4-hydroxylase alpha subunit-1 (P4HA1) and prolyl 4-hydroxylase beta subunit (P4HB) is provided. The disclosure provides a microorganism including a fusion protein comprising prolyl 4-hydroxylase alpha subunit-1 (P4HA1) and prolyl 4-hydroxylase beta subunit (P4HB); and another protein to be hydroxylated. A method for providing skincare benefits including applying the fusion protein of the present disclosure on skin is also taught.

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.

The present disclosure provides, in one embodiment, a method of treating or preventing an ID2 protein-related disease in a patient at risk of developing or having such a disease by administering to the patient a composition in an amount and for a time sufficient to increase degradation of HIFα in a cell affected by the ID2 protein-related disease in the patent and/or to decrease half-life of HIFα in the cell affected by the ID2 protein-related disease in the patient, as compared to an untreated cell affected by the ID2 protein-related disease.
