The circuitboard substrates are usually dielectric composite materials. Processivity is a characteristic of enzymes that function on polymeric substrates. It catalyzes the oxidation of various organic substrates by hydrogen peroxide. Dye ligand media is nonspecific but mimics biological substrates and proteins. Most of the fermentative substrates are organic molecules. Typically homogeneous catalysts are dissolved in a solvent with the substrates. Enzymes are usually much larger than their substrates. FLPs are also reactive toward many unsaturated substrates beyond H. Uncompetitive inhibition typically occurs in reactions with two or more substrates or products. They achieve this purpose by using different substrates and enzymes. Other types of matrix substrates and related processes are discussed below. The enzyme's sites serve as a communication between different substrates. The extracellular N-terminus is important in differentiating different types of binding substrates. This high-throughput system made use of reporter proteins fused with thousands of potential substrates independently. They can also be cultured in diverse unconventional chemical substrates.
