== Publication Abstract from PubMed ==
We report biochemical and structural studies on inhibiting bacterial S-adenosyl-L-homocysteine hydrolase by transition metal cations. Our results revealed diverse molecular mechanisms of enzyme inactivation. Depending on the cation, the mechanism is based on arresting the enzyme in its closed, inactive conformation, disulfide bond formation within the active site or oxidation of the intermediate form of a cofactor.

A closer look at molecular mechanisms underlying inhibition of S-adenosyl-L-homocysteine hydrolase by transition metal cations.,Gawel M, Malecki PH, Sliwiak J, Stepniewska M, Imiolczyk B, Czyrko-Horczak J, Jakubczyk D, Marczak L, Plonska-Brzezinska ME, Brzezinski K Chem Commun (Camb). 2024 Oct 8;60(81):11504-11507. doi: 10.1039/d4cc03143a.
