The subject invention relates in one aspect to an oxalate degrading composition, which includes at least one oxalate degrading enzyme. The composition includes an enriched insoluble component of fungal bio sample, and the composition is effective to degrade oxalate at a pH of 1.9 or higher. The composition is protected from protease degradation such as pepsin, trypsin and chymotrypsin. The composition is capable of withstanding the conditions of the stomach, small intestines, and/or large intestines of a subject.

Oxalate decarboxylase crystals, including stabilized crystals, such as cross-linked crystals of oxalate decarboxylase, are disclosed. Methods to treat a disorder associated with elevated oxalate concentration using oxalate decarboxylase crystals are also disclosed. Additionally disclosed are methods of producing protein crystals.

Methods and compositions related to the engineering of a protein with L-cyst(e)ine degrading enzyme activity are described. For example, in certain aspects there may be disclosed a modified cystathionine-γ-lyase comprising one or more amino acid substitutions and capable of degrading L-cyst(e)ine. Furthermore, certain aspects of the invention provide compositions and methods for the treatment of cancer with L-cyst(e)ine using the disclosed proteins or nucleic acids.

The present disclosure provides formulations for a drug product comprising a PEGylated CBS protein having the amino acid sequence of SEQ ID NO: 1. Dosages and dosing regimens are provided for treatment of homocystinuria in a subject in need thereof. Additionally, the dosages and dosing regimens are also provided to reduce the level of homocysteine (Hcy) or increase the levels of cysteine (Cys) and/or cystathionine (Cth) in a subject in need thereof.

Derivatives of Agrobacterium vitis strain F2/5 are disclosed. These derivatives were generated following homologous recombination with an internal fragment of targeted genes resulting in gene disruption by insertion of a copy of suicide vector pVIK165. The genes disrupted were F-avi5813 encoding a phosphopantetheinyltransferase, F-avi4329 encoding an aminotransferase and F-avi0838 (rirA) encoding an iron responsive transcriptional regulator. Such derivatives control crown gall on grapevines. In addition, these derivatives did not induce roots necrosis but enhanced root development and callus formation. On young stem explants, it was shown as well that the F2/5 derivatives are necrosis-negative.

In alternative embodiments, the invention provides compositions and methods for treating various disorders and conditions in mammals, including chronic disorders in which there is a presence of an abnormal microbiota or an abnormal distribution of microflora in the gastrointestinal tract. In alternative embodiments, the invention provides liquid preparations or formulations derived from a human fecal material (e.g., a stool) processed, e.g., filtered and/or centrifuged, such that all bacteria, fungal spores and viruses are removed, but retaining the native biologically active molecules from the fecal material and bacteriophages. In alternative embodiments, the invention provides a “rough-”, “incomplete-” or medium-filtered microbiota which still comprises native physiological components or nutritive agents for the bacteria, e.g., retains native biologically and nutritionally active components. In alternative embodiments, the invention provides a highly filtered or substantially purified microbiota in combination with, or having added back, a liquid preparation or formulation of the invention. In alternative embodiments, the invention provides compositions or formulations where the bacteria, or microbiota, component has been cultured, or cultured under anaerobic conditions, or harvested, stored and/or cultured under anaerobic conditions. In alternative embodiments, the invention provides various additives, compositions and donor restrictions for treating these disorders and conditions.
