Development of an improved cloning vector and transformation system in Amycolatopsis mediterranei (Nocardia mediterranei).
A versatile plasmid cloning vector pRL60 carrying kanamycin/neomycin resistance (km/neo), erythromycin resistance (ermE) and alpha-amylase (alpha-amy) marker genes that replicates in various Amycolatopsis mediterranei strains and Escherichia coli has been constructed. This cloning vector has been derived from a hybrid plasmid pRL50, which was developed by cloning ermE from pIJ4026 into a pRL1 d...

Bacteriol. 88:865-876. 1964.-Nutritionally complementary auxotrophic mutants derived from Nocardia erythropolis did not yield prototrophic recombinants when progeny from mixed cultures or newly mixed strains were inoculated onto minimal medium. Similarly, complementa...

متن کاملPurification and properties of glutamate synthase from Nocardia mediterranei.
Glutamate synthase was purified about 250-fold from Nocardia mediterranei U32 and characterized. The native enzyme has a molecular weight of 195,000 +/- 5,000 and is composed of two nonidentical subunits with molecular weights of 145,000 +/- 5,000 and 55,000 +/- 3,000. This enzyme is a complex of iron-sulfur flavoproteins with absorption maxima at 278, 375, 410, and 440 nm. It contains 1.1 mol ...
متن کاملStudy to the biosynthesis of the rifamycin-chromophore in Nocardia mediterranei.
Nocardia mediterranei produces the antibiotic rifamycin B, which belongs to the ansamycin group. The structure of rifamycin consists of the ansa chain and the chromophore. One part of this chromophore, the seven-carbon amino unit, which initiates ansa chain formation in ansamycins, has been identified as 3-amino-5-hydroxybenzoic acid. Kibby et al. 1] synthesized [carboxy-14C]3-amino-5hydroxyben...
