  • Publication number: 20170081692
    Abstract: The present invention relates to a method for producing a domain antibody in a yeast, wherein the formation of disulfide bridges in the domain antibody is promoted. The method encompasses the addition of oxidizing agents, preferably oxidizing metal ions, preferably one or more selected from Cu2+, Fe2+, Fe3+ and Zn2+.

  • Publication number: 20120157664
    Abstract: The present disclosure relates to a method for producing a domain antibody in a host other than E. coli, preferably yeast, comprising a) applying conditions that promote the formation of disulfide bridges in domain antibodies, or b) removing domain antibodies lacking at least one disulfide bridge, or c) a combination of (a) and (b).

  • Patent number: 7998720
    Abstract: The present invention is related to an isolated and purified enzyme with xylanolytic activity having more than 70% homology, preferably more than 80% homology with the amino acid sequence SEQ ID NO: 11.
    Type: Grant
    Filed: May 3, 2006

  • Publication number: 20110183861
    Abstract: Methods of modifying and in particular stabilizing proteins and polypeptides by which a predetermined amino acid is introduced into selected positions of said protein or polypeptide to produce a small group of mutants. The methods are based on the premise that certain amino acids play a crucial role in the stability of proteins or polypeptides. Generated mutants can then be further analysed for stability and/or function, e.g. affinity. Furthermore, appropriate mutants may be combined to result in further optimized proteins or polypeptides. In addition, stabilized example polypeptides and suitable methods to identify and/or analyse de-stabilized or stabilized proteins or polypeptides are provided. The methods can be used to study the role of specific amino acids in protein structure and function and to develop new or improved, e.g. stabilized proteins and polypeptides such as antibodies and single variable domains.
