An enzyme production line having a plurality of enzymes 3 bound to a support 4 for running a series of catalyzed reactions to convert a substrate 30 to a final product 32. A method of using the enzyme production line to form a final product 32 in which a substrate 30 contacts a first enzyme 3 bound to a support 4 to form an intermediate and contacting the intermediate with a second enzyme 3 bound to a support 4 to form a final product 32.

A nanoparticle (for example, quantum dot) serves as a substrate for immobilizing enzymes involved in consecutive reactions as a cascade. This results in a significant increase in the rate of catalysis as well as final product yield compared to non-immobilized enzymes.

Described herein are an immobilized enzyme, and a preparation method therefor and a use thereof. The immobilized enzyme includes activated PEI and an enzyme covalently bonded to the activated PEI, where the enzyme is selected from any one of a transaminase, a ketoreductase, a monooxygenase, an ammonia lyase, an ene-reductase, an imine reductase, an amino acid dehydrogenase and a nitrilase.

Polypeptide scaffolds comprising enzymatic proteins are provided. The enzymatic polypeptide scaffolds comprise heterologous enzymes to form a heterologous metabolic pathway, and can be targeted to a substrate through a surface anchoring domain. The enzymatic polypeptide scaffolds leverage the high specificity and affinity protein/protein interaction between the cohesins and dockerins of microorganismal cellulosomes to form custom enzymatic arrays.

Partial depletion of RLIP76 in p53 deficient living subject has shown many health benefits. In one embodiment, partical Rlip depletion is used to prevent or treat cancer in p53 deficient living subjects. In another embodiment, partial Rlip depletion is used for reversion of DNA-methylation abnormalities caused by the lack of p53 to normal in p53 deficient living subjects. In yet another embodiment, partial Rlip depletion is used in reduction of blood glucose, insulin-resistance, hyperlipidemina, or any combination thereof in p53 deficient living subjects. Methods of using liposome containing anti-sense nucleic acid or double stranded siRNA to partially deplete RLIP76 and thus treat p53 deficient subject are disclosed. The approaches described herein can be especially helpful in preventing cancer in Li-Fraumeni patients.

Multi-enzyme systems attached to nanoparticles are effective to efficiently and controllably incorporate stable isotopes (such as deuterium) during the synthesis of small molecules. In one example, deuterium is incorporated into (+)-dihydrocarvide using a cascade involving the enzymes (a) pentaerythritol tetranitrate reductase (PETNR) and (b) flavin-dependent cyclohexanone monooxygenase triple variant F249A/F280A/F435A (CHMO.sub.3M).
