摘要:
The invention provides a glutaryl 7-ACA amidase from Pseudomonas diminuta strain BS-203, which catalyzes the hydrolysis of 7-&bgr;-(4-carboxybutanamido)-cephalosporanic acid to 7-aminocephalosporanic acid and glutaric acid. The invention also provides nucleic acid sequences, vectors, and host cells useful in the production of this amidase. The glutaryl 7-ACA amidase can be used for the preparation of 7-aminocephalosporanic acid.
摘要:
Isolated nucleic acid sequences and polypeptides encoded thereby for epothilone B hydroxylase and mutants and variants thereof and a ferredoxin located downstream from the epothilone B hydroxylase gene are provided. Also provided are vectors and cells containing these vectors. In addition, methods for producing recombinant microorganisms, methods for using these recombinant microorganism to produce hydroxyalkyl-bearing epothilones and an epothilone analog produced by a mutant of epothilone B hydroxylase are provided.
