摘要:
The invention provides for compositions and methods for producing isoprene by using recombinantly engineered cells that utilize a system of dual IspG enzymes in addition to isoprene synthase.
摘要:
Described are variants of a parent alpha-amylase that exhibits an alteration in at least one of the following properties relative to said parent alpha-amylase: specific activity, substrate specificity, substrate binding, substrate cleavage, thermal stability, pH-dependent activity, pH-dependent stability, oxidative stability, calcium dependency, pI, and wash performance. The variants are suitable for starch conversion, ethanol production, laundry washing, dish washing, hard surface cleaning, textile desizing, and/or sweetener production.
摘要:
Described are variants (mutants) of a parent alpha-amylase having alpha-amylase activity and exhibiting altered properties relative to the parent alpha-amylase, and methods of use, thereof.
摘要:
The present invention relates to the use of a parent AmyTS-23 alpha-amylase as well as variants, which variant has alpha-amylase activity and exhibits altered properties relative to the parent alpha-amylase in the production of food products, such as the use in a baking composition.
摘要:
The present invention provides methods and compositions comprising at least one isoprene synthase enzyme with improved catalytic activity and/or solubility. In particular, the present invention provides variant plant isoprene synthases for increased isoprene production in microbial host cells. Biosynthetically produced isoprene of the present invention finds use in the manufacture of rubber and elastomers.

摘要:
The present invention provides cells that have been genetically manipulated to have an altered capacity to produce expressed proteins, wherein the pckA gene has been modified or deleted. In particular, the present invention relates to Gram-positive microorganisms, such as Bacillus species having enhanced expression of a protein of interest, wherein one or more chromosomal genes have been modified and/or inactivated (e.g., pckA), and preferably wherein one or more chromosomal genes (e.g., pckA) have been modified and/or deleted from the Bacillus chromosome. In some further embodiments, one or more indigenous chromosomal regions have been modified and/or deleted from a corresponding wild-type Bacillus host chromosome.
