Cross-Linked Enzyme Crystals (CLEC) offer a combination of the features normally associated with either enzymes (high activity and selectivity, ability to function under mild reaction conditions, ease of disposal) or heterogeneous catalysts (stability in different environments, recycling). CLEC has the excellent stability, activity, mechanical strength. CLEC catalysts are extremely useful in organic synthesis, especially in the resolution of chiral compounds, peptides synthesis, and the formation of C-C bonds.
