Abstract: Genetically modified HBc polypeptides are provided.

Abstract: The embodiments described herein pertain to cells, and methods for preparing cells, that can be used as biocatalysts by altering enzymes that compete for a substrate or product of a pathway of interest such that the targeted enzyme is sensitive to a site-specific protease, which protease is expressed but relocated in the cell to a site where it is not in contact with the targeted enzyme in the intact cell. Upon cell lysis, the protease contacts the target enzyme, which is then inactivated by protease cleavage.

Abstract: Genetically manipulated cells, lysates of such cells, systems, and methods of use thereof are provided, where one or more enzymes in a pathway of interest are genetically modified to incorporate a peptide sequence that provides for relocation of the protein, e.g., to the periplasm, so as to sequester the enzyme, and where the enzyme controls flux in the pathway of interest.

Abstract: The present disclosure relates, in some aspects, to cell-free methods and systems for large-scale conversion of methane to isobutanol, comprising combining, in a bioreactor at elevated pressure, methane, oxygen, and cell lysates containing methane monooxygenase, methanol dehydrogenase, and enzymes that catalyze the conversion of formaldehyde to isobutanol, to form a cell-free reaction mixture, and incubating under suitable conditions the cell-free reaction to convert methane to isobutanol.

Abstract: Vaccine compositions and methods of producing and using the same are provided, which compositions comprise a modified HA stem domain in a trimeric configuration.

Abstract: Methods are provided for controlling metabolic flux rate in a cell-free system comprising a complex set of enzymes, to produce a desired product of a pathway of interest. In the methods of the invention, measurements of metabolic performance parameters are taken by continuous monitoring or intermittent monitoring. Based on the metabolic performance parameters, the system is modified by one or more steps comprising: (i) altering enzyme levels in the cell-free system; (ii) altering feed rate of a substrate that controls redox flux or carbon flux to the cell-free system; (iii) altering O2 addition to the cell-free system; (iv) controlling efficiency of electron transport system by altering leakage across a membrane; wherein enzymes present in the pathway of interest catalyze production of a desired product.

Abstract: Methods are provided for a one step synthesis of polypeptide polymers or co-polymers. The polymers or co-polymers can be linear or branched. In the methods of the invention, the coding sequence for the polypeptide(s) to be polymerized is altered by introducing one or more codons for an nonnatural amino acid, which coding sequence is then utilized to produce the cognate polypeptide. The nonnatural amino acids are selected to be reactive with each other in a bioorthogonal reaction, and are combined in a conjugation reaction with the desired components of the polymer.

Abstract: Compositions of a fusion protein comprising a spatially tethered ferredoxin-NADP-reductase (FNR) and an active [FeFe] hydrogenase, genetic sequences encoding such fusion proteins, and methods of use thereof are provided. The fusion proteins of the invention link an FNR polypeptide to an active [FeFe] hydrogenase through a polypeptide linker. The fusion protein facilitates improved electron transfer through a ferredoxin, and allows direct electron transfer from NADPH to the hydrogenase.
