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 2.8.1.6 L-methionine 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. 88 2.8.1.6 additional information not inhibitory: pyridoxal 5’-phosphate, deoxyadenosine 2 2.8.1.6 additional information 5'-methylthioadenosine is not an inhibitor.
