Haoran’s paper is published in JACS.

Haoran’s paper about the catalytic function of the auxiliary cluster of MoaA is now published online on JACS.  In this work we determined the reduction potentials of the two 4Fe-4S clusters in MoaA and compared them with theoretical reduction potentials of the putative aminyl radical intermediate. The results suggested PCET mechanism for the aminyl radical reduction. Furthermore, the EPR characterization of the C4′ radical revealed an electronic coupling between GTP and the auxiliary cluster, suggesting a potentially missing mechanism of catalysis.
