A Water-Bridged H-Bonding Network Contributes to the Catalysis of the SAM-Dependent C-Methyltransferase HcgC

Xile Hu, Tao Xu, Lichen Bai

[Fe]-hydrogenase hosts an iron-guanylylpyridinol (FeGP) cofactor. The FeGP cofactor contains a pyridinol ring substituted with GMP, two methyl groups, and an acylmethyl group. HcgC, an enzyme involved in FeGP biosynthesis, catalyzes methyl transfer from S- ...

Nonsteroidal Anti-inflammatory-Organometallic Anticancer Compounds

Paul Joseph Dyson, Rosario Scopelliti, Emilia Paunescu, Mylène Soudani

Compounds that combine metal-based drugs with covalently linked targeted organic agents have been shown, in some instances, to exhibit superior anticancer properties compared to the individual counterparts. Within this framework, we prepared a series of or ...
