Abstract: The present invention relates to trehalose phosphorylases which are useful for the industrial production of trehalose-analogs and glycosyl phosphates. More specifically, the invention discloses trehalose phosphorylases which are mutated in specific amino acid regions. These specific mutations result in modified substrate specificities of the enzymes. In addition, the present invention discloses a wild type trehalose phosphorylase from the marine organism Caldanaerobacter subterraneus, and mutated types thereof, which are highly thermostable and have a broad acceptor and donor specificity.

Abstract: The invention belongs to the field of functional proteomics and, more particularly, to the field of protein aggregation. Described are methods for interfering with the function of a target protein and uses a non-naturally, user-designed molecule, designated as interferor, that has a specificity for a target protein and that induces aggregation upon contact with the target protein. The invention also discloses such interferer molecules and their use in therapeutic applications.
Abstract: The present invention provides for the improved production of fatty acid products in a recombinant microorganism or host cell engineered to express a non-native gene encoding a thioesterase and a non-native gene encoding a lysophosphatidic acid acyltransferase (LPAAT), in which the LPAAT is overexpressed in the recombinant microorganism compared to an otherwise identical microorganism that does not include the non-native LPAAT gene. The invention also provides methods of producing fatty acid products using such recombinant microorganisms.

Abstract: The present invention relates to a process for integrated production of ethanol and seaweed biofertilizer from fresh red seaweed, Kappaphycus alvarezii. Specifically, the present invention describes a process for the production of ethanol, as a byproduct, from Kappaphycus alvarezii. The process includes crushing the fresh weeds to release the sap, a proved biofertilizer, and recovering the residual carrageenan rich biomass, hydrolyzing the biomass using dilute acid at elevated temperature, neutralizing the hydrolysate by using inexpensive calcium hydroxide and removing the insoluble salts through filtration or centrifugation, desalting soluble salts from the hydrolysate by electrodialysis, enriching with nitrogen source, inoculating with yeast and fermenting it to form a fermented broth containing ethanol and separating ethanol from the fermented broth by distillation and using residual hydrolysate, generated CaSO4 and reject obtained from electrodialysis as manure.

Abstract: Methods and systems for computationally designing self-assembling polypeptides are disclosed. A representation of a docked configuration of a symmetric protein architecture can be determined by a computing device configured to computationally symmetrically dock representations of protein building blocks within a representation of a symmetric protein architecture, where symmetrically docking a representation of a particular protein building block can include determining a configuration of the protein building blocks in three-dimensional space within the symmetric protein architecture configured to generate interfaces between building blocks suitable for computational protein interface design. The amino acid sequence of the docked protein building blocks can be computationally modified to specify protein-protein interfaces between the plurality of protein building blocks that are energetically favorable to drive self-assembly of a protein that includes the modified amino acid sequence.
