چکیده
A number of minor compounds were isolated from fermentations of the protorifamycin I producing strain Nocardia mediterranei F 1/24(1,2)) and identified by means of chemical and spectroscopic methods. Two types of structures were identified: Type 1: modified protorifamycins (derived from protorifamycin I) Type 2: defective rifamycins (8-deoxyrifamycins).

Characterization of the early stage aminoshikimate pathway in the formation of 3-amino-5-hydroxybenzoic acid: the RifN protein specifically converts kanosamine into kanosamine 6-phosphate.
The biosynthesis of 3-amino-5-hydroxybenzoic acid (AHBA), precursor of the ansamycin and mitomycin antibiotics, proceeds by the aminoshikimate pathway from 3,4-dideoxy-4-amino-D-arabino-heptulosonic acid 7-phosphate (aminoDAHP). Identification of RifN, product of one of three genes from the rifamycin biosynthetic gene cluster known to be essential for aminoDAHP formation, as a specific kanosami...
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...
متن کاملAnsamycin biogenesis: studies on a novel rifamycin isolated from a mutant strain of Nocardia mediterranei.
A novel ansamycin, rifamycin W, was isolated from a mutant strain of Nocardia mediterranei. The metabolic origin of rifamycin W was studied by (13)C nuclear magnetic resonance spectroscopy. Examination of the proton-decoupled pulse and Fourier transform (13)C spectra of rifamycin W biogenetically enriched with [1-(13)C]-, [2-(13)C]-, and [3-(13)C]propionate and with [1-(13)C]acetate has reveale...

During one year period from 2010 to 2011 the samples from pneumonic animals were taken and transported to the laboratory. Pasteurella multocida were identified in 16.6% of animal by biochemical test. The high incidence of P. multocida was obtained in the south of Fars province, where the area was warm region. The Mean Death Time between the isolates was 12-18 and 19-24 hours. Only the capsular ...
