... An enzyme may not work if its environment is changed. Both models of enzyme action depend on an exact fit between the active site of an enzyme and the substrate to which it binds. If anything were to block the active site or change the shape of the protein (enzyme), it could prevent the enzyme from ...

Novel Specific Halogenating Enzymes from Bacteria
... All isolated bacterial and eukaryotic halo peroxidases only showed very low or no substrate specificity at all (Franssen, 1994). However, as haloperoxidases were the only halogenating enzymes known, with the exception of some Sadenosyl methionine transferases that are involved in the formation of m ...
