  Electrochemical Resolution of the [4Fe-4S] Centers of the AdoMet Radical Enzyme BtrN: Evidence of Proton Coupling and an Unusual, Low-Potential Auxiliary Cluster

  摘要：

  The S-adenosylmethionine (AdoMet) radical superfamily of enzymes includes over 113 500 unique members, each of which contains one indispensable iron-sulfur (FeS) cluster that is required to generate a 5'-deoxyadenosyl 5'-radical intermediate during catalysis. Enzymes within several subgroups of the superfamily, however, have been found to contain one or more additional FeS clusters. While these additional clusters are absolutely essential for enzyme activity, their exact roles in the function and/or mechanism of action of many of the enzymes are at best speculative, indicating a need to develop methods to characterize and study these clusters in more detail. Here, BtrN, an AdoMet radical dehydrogenase that catalyzes the two-electron oxidation of 2-deoxy-scyllo-inosamine to amino-dideoxy-scyllo-inosose, an intermediate in the biosynthesis of 2-deoxystreptamine antibiotics, is examined through direct electrochemistry, where the potential of both its AdoMet radical and auxiliary [4Fe-4S] clusters can be measured simultaneously. We find that the AdoMet radical cluster exhibits a midpoint potential of -510 mV, while the auxiliary cluster exhibits a midpoint potential of -765 mV, to our knowledge the lowest [4Fe-4S](2+/+) potential to be determined to date. The impact of AdoMet binding and the pH dependence of catalysis are also quantitatively observed. These data show that direct electrochemical methods can be used to further elucidate the chemistry of the burgeoning AdoMet radical superfamily in the future.

  derivative, designated nabscessin C (1), was isolated from Nocardia abscessus IFM 10029T. Nabcessin C is an isomer of nabscessins A (2) and B (3) with different positioning of the acyl group. Absolute configuration of nabscessin A was determined by conversion into the 2-deoxy-scyllo-inosamine pentaacetyl derivative (4) by hydrolysis and acetylation of 2. The biosynthetic pathway of nabscessins is proposed

  2-Deoxystreptamine (DOS)-containing aminoglycoside-aminocyclitol (AmAc) antibiotics represent the majority of clinically important AmAcs. Biosynthetic investigations of formation of DOS in actinomycetes are limited to the characterization of 2-deoxy-scyllo-inosose synthase, the first step enzyme of the DOS biosynthetic pathway. A gene encoding L-glutamine:2-deoxy-scyllo-mosose aminotransferase (tbmB) from the tobramycin producer Streptomyces tenebrarius was expressed heterologously in Escherichia coli. The conversions of 2-deoxy-scyllo-inosose to 2-deoxy-scyllo-inosamine and scyllo-inosose to scyllo-inosamine with the activity of TbmB were determined in vitro. The results indicate that tbmB catalyzes the second step of the DOS biosynthetic pathway during the biosynthesis of 2-deoxystreptamine, a subunit of tobramycin, in S. tenebrarius.
