WebMay 18, 2024 · The substrates of a catalyzed biochemical reaction are bound to, and held in place on the enzyme while rapid bond rearrangements take place. Because of their flexibility, enzymes undergo change in shape at the active site during catalysis itself. WebA restriction enzyme is a DNA-cutting enzyme that recognizes specific sites in DNA. Many restriction enzymes make staggered cuts at or near their recognition sites, producing ends with a single-stranded overhang. If two … WebWhen an enzyme binds its substrate it forms an enzyme-substrate complex. Enzymes promote chemical reactions by bringing substrates together in an optimal orientation, thus creating an ideal chemical environment for the reaction to occur.
