2.8.1.6 5'-deoxyadenosine strong inhibitor, reversible, 90% inhibition upon addition of 1 equivalent of 5'-deoxyadenosine with regard to the enzyme 943 2.8.1.6 5'-deoxyadenosine product inhibition. The combination of both products in equimolar concentrations results in more than simple additive inhibition, suggesting that they bind cooperatively to the enzyme. 943 2.8.1.6 5'-deoxyadenosine competitive, inhibits the growth of Mycobacterium tuberculosis H37Ra with an MIC of 392.6 microg/ml 943 2.8.1.6 acidomycin structural analog of biotin, complete inhibition at 0.4 mM, 50% inhibition at 0.035 mM 115159 2.8.1.6 acidomycin acidomycin inhibits biotin synthesis through the competitive inhibition of biotin synthase BioB and also stimulates unproductive cleavage of S-adenosyl-L-methionine to generate the toxic metabolite 5'-deoxyadenosine. Acidomycin selectively accumulates in Mycobycterium tuberculosis. The development of spontaneous resistance by Mycobacterium tuberculosis to acidomycin is difficult, and only low-level resistance to acidomycin is observed by overexpression of BioB 115159 2.8.1.6 Cd2+ 1 mM, almost complete inhibition 52 2.8.1.6 Co2+ 1 mM, almost complete inhibition 23 2.8.1.6 Cu2+ 1 mM, almost complete inhibition 19 2.8.1.6 Fe2+ above 1 mM 25 2.8.1.6 Hg2+ 1 mM, almost complete inhibition 33
