The latest short science news items from C&EN. The team proposes that SAM plays a dual role in the reaction. It donates a methyl group to the enzyme’s cobalamin cofactor and then serves as a base when ...

Although many organisms capture and respond to sunlight, enzymes - proteins that catalyze biochemical reactions - are rarely driven by light. A new study captures the full cycle of complex structural ...

Cells use flavin monooxygenases to break down foreign molecules by adding oxygen atoms to them. Biochemists have long assumed that the enzymes use a particular cofactor adduct to add the oxygen. A new ...
