Synthesis and Characterization of Phosphorus- and Carborane-Containing Polyoxanorbornene Block Copolymers.

Grubbs-catalyzed ring-opening metathesis polymerization (ROMP) of carborane- and phosphonate-containing monomers has been used for the generation of hybrid block copolymers. Molecular weights with M of 50,000 g/mol were readily obtained with polydispersity index values, Đ, between 1.03⁻1.

Two dedicated class C radical S-adenosylmethionine methyltransferases concertedly catalyse the synthesis of 7,8-dimethylmenaquinone.

Dimethylmenaquinone (DMMK), a prevalent menaquinone (MK) derivative of uncertain function, is characteristic for members of the class Coriobacteriia. Such bacteria are frequently present in intestinal microbiomes and comprise several pathogenic species. The coriobacterial model organism Adlercreutzia equolifaciens was used to investigate the enzymology of DMMK biosynthesis.
