This concept is similar to the principle of preorganization which states that complexation could be improved if the binding motifs are preorganized in a well-defined position so that the host does not require any major conformational change for complexation. In this case, the catalyst is preorganized such that no major conformational changes is required for the reaction to occur. A notable example of catalysts that employ this mechanism is Jean-Marie Lehn's crown ether. In addition, catalysts based on functionalized cyclodextrins often employ this mode of catalysis.

In 2005, A. De Lencastre et al. found that during splicing of Group II introns, all reactants are preorganized before the initiation of splicing. The branch site, both exons, the catalytically essential regions of DV and J2/3, and ε−ε' are in close proximity before the first step of splicing occurs. In addition to the bulge and AGC triad regions of DV, the J2/3 linker region, the ε−ε' nucleotides and the coordination loop in DI are crucial for the architecture and function of the active-site.

The roof of the active site is characterized by conserved base triples, which connect P2.1 and P2.2 stacks and the floor consists of a non-conserved G-U pair, which are splayed apart. By examining superimposition of ribozyme structures in a pre-cleavage state, metabolite bound state and post cleavage state, it was determined there is no gross conformational change upon metabolite binding, which is indicative of a preorganized active site that depends on GlcN6P as a cofactor, not an allosteric activator. The cofactor is bound in a solvent-accessible pocket and the structure suggests that the amine group of GlcN6P is involved in the catalytic process.
