研究结论

Date Results Publications
2011-11-05 11:11:00 In biotin synthase, abstraction of a hydrogen atom from the C9 methyl group of dethiobiotin results in formation of a dethiobiotinyl methylene carbon radical, which is quenched by a sulfur atom to form a new carbon-sulfur bond in 9-mercaptodethiobiotin. 21859080
2010-04-12 12:18:00 Asparagine 153 and aspartate 155 of bioB are important for retaining intermediates during the catalytic cycle. 19199517
2010-01-21 00:00:00 mutants of highly conserved residues from the Y(150)NHNLD motif are inactive & are also unable to cleave AdoMet and to produce the deoxyadenosyl radical (AdoCH(2)(*)). 17014080
2010-01-21 00:00:00 It is proposed that the [2Fe-2S]2+ cluster of biotin synthase is both the sulfur-donating substrate and the sulfur-oxidizing cofactor, but each round of catalysis generates an inactive enzyme in which this cluster has been destroyed. 18155152
2010-01-21 00:00:00 mutations in the conserved YNHNLD sequence of Escherichia coli BioB affect the formation and stability of the [4Fe-4S](1+) cluster on reduction with dithionite and report the observation of a new [2Fe-2S](1+) cluster. 19245793
