(1) Only then can the catalytic activity, for which both are programmed, be set in motion.

(2) This is why crystallised enzymes often retain their catalytic activities.

(3) The catalytic region of the enzyme, called the active site, is a very small pocket on its outer surface.

(4) Their implications for catalytic function and ligand interaction are discussed.

(5) The dimer, which maintains catalytic activity, was used throughout our studies.

(6) It was the first RNA molecule to be shown to have a catalytic activity and has since been studied in great detail.

(7) If even one amino acid in the enzyme is changed, the enzyme may lose its catalytic activity.

(8) It is frequently reported that a crystalline enzyme retains some catalytic activity.

(9) Gene therapy is also making use of catalytic RNA through the construction of ribozymes.

(10) His theory was that irregularities in clay sheets could have acted as catalytic surfaces, as well as providing a template on which new clay could be added.

(11) The association of the monomers may affect the catalytic activity of the enzyme.

(12) As expected, these catalytic residues are fully conserved at the amino acid level.

(13) Pre catalyzed lacquers have the catalytic agent added to the lacquer at the factory.

(14) Such a development might be useful in stereoselective catalytic syntheses.

(15) Obviously, the catalytic residues of an enzyme are key to its molecular function.

(16) This mutant contains a single amino acid substitution in the nuclease catalytic center of RecB.

(17) The first catalytic converters used mainly platinum, but now palladium is the predominant catalytic metal.

(18) Many organic molecules undergo structural changes as a result of catalytic reactions with acid or base.

(19) Traces of metal ions (which could act as catalytic redox centres) were similarly ruled out.

(20) His study elucidated the effects of ligand structure and electronics on catalytic activity.
