The genes involved in AHBA formation were inactivated individually, and the resulting mutants were further examined by incubating the cell-free extracts with known intermediates of the pathway and analyzing for AHBA formation. The rifL, -M, and -N genes were shown to be involved in the step(s) from either phosphoenolpyruvate/d-erythrose 4-phosphate or other precursors to 3,4-dideoxy-4-amino-d-arabino-heptulosonate 7-phosphate. The gene products of the rifH, -G, and -J genes resemble enzymes involved in the shikimate biosynthesis pathway (August, P. R., Tang, L., Yoon, Y. J., Ning, S., Müller, R., Yu, T.-W., Taylor, M., Hoffmann, D., Kim, C.-G., Zhang, X., Hutchinson, C. R., and Floss, H. G. (1998) Chem. Biol. 5, 69-79). Mutants of the rifH and -J genes produced rifamycin B at 1% and 10%, respectively, of the yields of the wild type; inactivation of the rifG gene did not affect rifamycin production significantly. Finally, coexpressing the rifG-N and -J genes in S. coelicolor YU105 under the control of the act promoter led to significant production of AHBA in the fermented cultures, confirming that seven of these genes are indeed necessary and sufficient for AHBA formation. The effects of deletion of individual genes from the heterologous expression cassette on AHBA formation duplicated the effects of the genomic rifG-N and -J mutations on rifamycin production, indicating that all these genes encode proteins with catalytic rather than regulatory functions in AHBA formation for rifamycin biosynthesis by A. mediterranei. 000033246 536__ $$0G:(DE-Juel1)FUEK93$$2G:(DE-HGF)$$aVerfahrenstechnik zur mikrobiellen Gewinnung von Primärmetaboliten$$c41.40.0$$x0 000033246 588__ $$aDataset connected to Web of Science, Pubmed 000033246 650_2 $$2MeSH$$aActinomycetales: enzymology 000033246 650_2 $$2MeSH$$aActinomycetales: genetics 000033246 650_2 $$2MeSH$$aAmino Acid Sequence 000033246 650_2 $$2MeSH$$aAminobenzoic Acids: metabolism 000033246 650_2 $$2MeSH$$aBase Sequence 000033246 650_2 $$2MeSH$$aDNA Mutational Analysis: methods 000033246 650_2 $$2MeSH$$aDNA Primers 000033246 650_2 $$2MeSH$$aGenes, Bacterial 000033246 650_2 $$2MeSH$$aGenes, Regulator 000033246 650_2 $$2MeSH$$aMolecular Sequence Data 000033246 650_2 $$2MeSH$$aMultigene Family 000033246 650_2 $$2MeSH$$aOpen Reading Frames 000033246 650_2 $$2MeSH$$aPlasmids 000033246 650_2 $$2MeSH$$aPromoter Regions, Genetic 000033246 650_2 $$2MeSH$$aRestriction Mapping 000033246 650_2 $$2MeSH$$aRifabutin: metabolism 000033246 650_2 $$2MeSH$$aRifamycins: biosynthesis 000033246 650_7 $$00$$2NLM Chemicals$$aAminobenzoic Acids 000033246 650_7 $$00$$2NLM Chemicals$$aDNA Primers 000033246 650_7 $$00$$2NLM Chemicals$$aRifamycins 000033246 650_7 $$072559-06-9$$2NLM Chemicals$$aRifabutin 000033246 650_7 $$076045-71-1$$2NLM Chemicals$$a3-amino-5-hydroxybenzoic acid 000033246 650_7 $$2WoSType$$aJ 000033246 7001_ $$0P:(DE-HGF)0$$aMüller, R.$$b1 000033246 7001_ $$0P:(DE-Juel1)VDB1106$$aMüller, M.$$b2$$uFZJ 000033246 7001_ $$0P:(DE-HGF)0$$aFloss, H.
