摘要:
The present invention provides an inexpensive fermentation medium for growing microorganisms. Also provided are fermentation media and methods for producing norleucine by growing E. coli thereon, fermentation media and methods for incorporating norleucine into polypeptides expressed by microorganisms grown thereon, and fermentation media and methods for preventing the incorporation of norleucine into polypeptides expressed by microorganisms grown thereon. Also provided are bovine somatotropin analogs.

摘要:
The present invention is based upon the discovery that proteins made from genes that include the CD4 sequence in its cDNA can make additional polypeptides as a result of internal translation initiation. This invention is thus directed to DNA sequences which eliminate internal initiation expression in sCD4.
摘要:
Disclosed are expression vectors useful as vectors in recombinant methods to facilitate expression of exogenous genes in E. coli. Specifically, the disclosed expression vector has the following elements in operable linkage: the PL6m promoter, the TAT32 ribosome binding site and a gene encoding a heterologous polypeptide, Also disclosed are E. coli host cells transformed with this expression vector.
