Abstract:
The invention provides methods and compositions for improved protein production. The method comprises the steps of: (a) introducing into a host cell a first nucleic acid sequence comprising a signal sequence operably linked to a desired protein sequence; (b) expressing the first nucleic acid sequence; (c) co-expressing a second nucleic acid sequence encoding a chaperone or foldase selected from the group consisting of bip1, ero1, pdi1, tig1, prp1,ppi1, ppi2, prp3, prp4 , calnexin, and Ihs1 ; and (d) collecting the desired protein secreted from the host cell. The first nucleic acid sequence optionally comprises an enzyme sequence between the signal sequence and the desired protein sequence.
Abstract:
The invention relates to a filamentous fungal cell (e.g., Aspergillus sp.) comprising at least one inactivated protease gene chosen from apsB, a homolog of apsB, cpsA, a homolog cpsA, and combinations thereof. Nucleic acids and methods for making the inactivated mutant filamentous fungal cells are provided as well as methods for using the cells for the altered production of endogenous or heterologous proteins of interest.
Abstract:
Novel laccase mediators, including carboxyamido and cyano derivatives of 2, 6-dimethoxyphenol that exhibit improved hydrolytic stability and good bleaching performance. The novel laccase enzymes may be employed in conjunction with the 2,6-dimethoxyphenol derivatives of this invention to provide an improved method for bleaching denim fabrics.
Abstract:
The present compositions, methods, and systems, relating to variant laccase enzymes that demonstrate increased expression and/or activity compared to a reference parental laccase enzyme. The variant enzymes include mutations that affect glycosylation, surface charge, or surface hydrophobicity, resulting in improved enzyme expression and/or enzyme activity.
Abstract:
Novel laccases, nucleic acid sequences encoding such laccases, and vectors and host cells for expressing the laccases are described. The novel laccase enzymes may be employed in conjunction with mediators to provide an improved method for bleaching denim fabrics.
Abstract:
Laccase enzymes and nucleic acid sequences encoding such laccase enzymes are described. The laccase enzymes may be employed in conjunction with mediators in improved methods for modifying the color of denim fabrics. Low temperature and single-bath textile processing using laccase enzymes are also described.
Abstract:
A filamentous fungal cell is provided comprising at least one mutation, wherein the filamentous fungal cell has impaired ptrB activity and has altered expression of a protein of interest as compared to a corresponding parent filamentous fungal cell. In one embodiment, the altered expression of the protein of interest is enhanced expression of the protein of interest.
Abstract:
