摘要:
Antimicrobial modified defensin or defensin-like peptides, modified C-terminal fragments of a defensin or defensin-like peptides and nucleic acids encoding the same are disclosed. Compositions comprising the defensin variant peptides and methods of their use to control microbial infections of plants and vertebrate subjects as well as contamination of feedstuffs and foodstuffs are also disclosed.
摘要:
Disclosed is a process for the production of a desired oligosaccharide, the process comprises providing a genetically engineered microbial cell which possesses a saccharide importer for the uptake of an intermediate oligosaccharide, and an enzyme being able to convert the intermediated oligosaccharide by transferring a monosaccharide moiety from a donor substrate to the intermediate oligosaccharide; cultivating the genetically engineered microbial cell in the presence of an intermediate oligosaccharide to generate the desired oligosaccharide; and retrieving the desired oligosaccharide.
摘要:
The present invention relates to methods for producing Saccharomyces strains that are capable of growth on xylose as a sole carbon source at a desired growth rate, (such as at least one generation per 48 hours), strains made by such methods, and Saccharomyces strains that grow at a growth rate of at least one generation per 48 hours using xylose as a sole carbon source for growth made by non-recombinant methods.

摘要:
The present invention aims to supply yeasts suitable for breadmaking using a large amount of yeast, as well as compositions that can give a bakery product containing said yeasts. The present invention also relates to a method of preparing a bakery product and a method of selecting yeast strains giving yeasts suitable for breadmaking using a large amount of yeast.
摘要:
The present invention relates to a process for synthesizing oligosaccharides. The process involves contacting an acceptor moiety with unpurified sugar-nucleotides and/or unpurified glycosyltransferase to synthesize oligosaccharides.
摘要:
The invention relates to the human herpesvirus type 6 protein p100 and parts thereof having its specific immunological properties. It further relates to antibodies directed to them and to the corresponding DNA sequences. They can be used in pharmaceutical or diagnostic compositions, optionally together with other HHV-6 proteins or the corresponding DNA sequences.
摘要:
This invention relates to E2 trans-activation repressors which interfere with normal functioning of the native full-length E2 transcriptional activation protein of the papillomavirus. Native full-length E2 trans-activation protein activates transcription of papillomavirus only through binding to DNA, and it binds to DNA only in the form of a pre-formed homodimer--a pair of identical polypeptide subunits held together by non-covalent interactions. The E2 trans-activation repressors of this invention are proteins, polypeptides or other molecules that dimerize with full-length native E2 polypeptides to form inactive heterodimers, thus interfering with the formation of active homodimers comprising full-length native E2 polypeptides, thereby repressing papillomavirus transcription and replication. The E2 trans-activation repressors of this invention are advantageously used in the treatment of papillomavirus infections and their associated diseases.
摘要:
A gene which provides resistance to at least one methionine derivative and is capable of enhancing accumulation of S-adenosyl-L-methionine (SAM) in a cell, a hybrid plasmid having the same, a cell transformed with the above hybrid plasmid, and a process for producing SAM using the above cell. According to the present invention, SAM, which has various therapeutic effects, can be producing in a large amount at a low cost.
摘要:
A process for preparing an optically active .gamma.-halo-.beta.-hydroxybutyric acid ester in high yields which comprises subjecting a .gamma.-haloacetoacetic acid ester to the action of a microorganism selected from genus Saccharomyces under an anaerobic condition. When the .gamma.-haloacetoacetic acid ester is subjected to the action of the microorganism in the presence of a ketal, the yield and optical purity can be further increased.
