摘要:
An amphibian egg extract is added to a cell-free translation system to obtain in vitro translocation and processing of newly synthesized peptide. The egg extract produces near complete signal sequence and N-linked carbohydrate processing of protein. Egg extract microsomes provide for protein translocation.
摘要:
Recombinant materials for the production of practical amounts of the sweet protein, mabinlin are provided. In addition, transgenic plants which have inherently sweetened edible parts result from modifying native plants containing edible parts to express the mabinlin gene. Single-chain forms of this protein which retain their sweetening property are also provided.
摘要:
The present invention provides improved host cells for use in producing secreted recombinant proteins, methods of making the improved hosts and uses thereof. The invention specifically provides strains of Neurospora crassa which produce reduced levels of extracellular proteases when compared with wild-type Neurospora crassa.
摘要:
The present invention is directed to methods and reagents for the specific detection and presumptive identification of various bacteria associated with waterborne infectious disease. In particular, this invention relates to methods and reagents for the specific detection and identification of Salmonella and Shigella in environmental samples such as water and sewage.
摘要:
Modified forms of human serum albumin (HSA) wherein the arginine at position 218 is substituted by a less basic amino acid show strong thyroxin-binding activity. These modified forms of HSA and fragments thereof are useful in binding thyroxin in standard assays for free thyroxin concentration and in treating conditions characterized by higher-than-desired levels of free thyroxin in animal subjects.

摘要:
New hapalindole-type alkaloids called A89271 A-F and I are antifungal and antitumor agents. Methods for preparing them and for preparing hapalindoles G and H by culturing the blue-green alga Fischerella ambigua ATCC 55210 are provided. Methods for preparing A89271 factors B and F by culturing the blue-green alga Hapalosiphon hibernicus ATCC 55225 and a biologically pure culture of this alga are also provided. Further provided are methods and compositions for the inhibition of fungal growth and the treatment of susceptible neoplasms.
摘要:
A seawater deaerator has a large reservoir through which seawater slowly flows. Gas is injected into the bottom of the reservoir through porous aeration stones forming bubble nuclei. The seed bubbles move upward through the seawater in the reservoir expanding but not coalescing, and withdrawing dissolved gas from the seawater. The deaerated seawater flows out of the reservoir and subsequently flows through spouts into a flash evaporator. Gas is withdrawn from a low pressure gas chamber at the top of the reservoir by a vacuum pump. The exhaust of the vacuum pump supplies gas to the air injectors.
