Substrat channeling
Web22 Mar 2016 · Substrate channeling has been shown in other systems to limit the diffusion of intermediates into the cytosol as well as to protect labile intermediates from degradation [13]. We further ... Web24 Feb 2024 · Metabolite or substrate channeling means a direct transfer of the product of one enzyme to another in a cascade reaction, without releasing it into the bulk solution [ 8 – 12 ]. This is realized through formation of enzyme-enzyme complexes, also called enzyme assemblies or metabolons.
