Early intermediates in the biosynthesis of ansamycins. I. Isolation and identification of protorifamycin I.
Ghisalba O, Traxler P, Nüesch J. Ghisalba O, et al. J Antibiot (Tokyo). 1978 Nov;31(11):1124-31. doi: 10.7164/antibiotics.31.1124. J Antibiot (Tokyo). 1978. PMID: 721708 Free article.
A mutant strain derived from Nocardia mediterranei N813 was found to accumulate a number of novel ansamycins structurally related to the protostreptovaricins and to rifamycin W. One of the main components of this ansamycin complex, protorifamycin I (8-deoxyrifamycin W), wa …

Early intermediates in the biosynthesis of ansamycins. II. Isolation and identification of proansamycin B-M1 and protorifamycin i-M1.
Ghisalba O, Traxler P, Fuhrer H, Richter WJ. Ghisalba O, et al. J Antibiot (Tokyo). 1979 Dec;32(12):1267-72. doi: 10.7164/antibiotics.32.1267. J Antibiot (Tokyo). 1979. PMID: 396289 Free article.
Proansamycin B-M1 and protorifamycin I-M1 were isolated as minor compounds from fermentations of the protorifamycin I producing strain Nocardia mediterranei F 1/24, identified by means of chemical and spectroscopic methods and shown to be degradation products of the …

Bioprospecting for the soil-derived actinobacteria and bioactive secondary metabolites on the Western Qinghai-Tibet Plateau.
Liu L, Liu Y, Liu S, Nikandrova AA, Imamutdinova AN, Lukianov DA, Osterman IA, Sergiev PV, Zhang B, Zhang D, Li F, Sun C. Liu L, et al. Front Microbiol. 2023 Oct 11;14:1247001. doi: 10.3389/fmicb.2023.1247001. eCollection 2023. Front Microbiol. 2023. PMID: 37886074 Free PMC article.
The secondary metabolites produced by strain A133 was annotated as rifamycins and zampanolides by antiSMASH and GNPS analysis. Five members of rifamycins, including rifamycin W, protorifamycin I, rifamycin W-M1, proansamycin B, and rifamycin S, were purified and identified …

Early intermediates in the biosynthesis of ansamycins. III. Isolation and identification of further 8-deoxyansamycins of the rifamycin-type.
Ghisalba O, Traxler P, Fuhrer H, Richter WJ. Ghisalba O, et al. J Antibiot (Tokyo). 1980 Aug;33(8):847-56. doi: 10.7164/antibiotics.33.847. J Antibiot (Tokyo). 1980. PMID: 7000738 Free article.
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 …
