Towns in Luxembourg Kynureninase or L-Kynurenine hydrolase (KYNU) () is a PLP dependent enzyme that catalyses the cleavage of kynurenine (Kyn) into anthranilic acid (Ant).

This enzyme catalyses the following chemical reaction.

Generally, TdT catalyses the addition of nucleotides to the 3' terminus of a DNA molecule.

Such cases exist: for example a mutase such as phosphoglucomutase catalyses the transfer of a phospho group from one position to another, and isomerase is a more general term for an enzyme that catalyses any one-substrate one-product reaction, such as triosephosphate isomerase.

However, such enzymes are not very common, and are heavily outnumbered by enzymes that catalyse two-substrate two-product reactions: these include, for example, the NAD-dependent dehydrogenases such as alcohol dehydrogenase, which catalyses the oxidation of ethanol by NAD+.

We consider the case of an enzyme that catalyses the reaction in both directions:.

Aureusidin synthase catalyses the aromatization and cyclization of the newly added carbonyl groups and facilitates the release of CoA to reform the carboxylic acid.

The enzyme guanosyl transferase then catalyses the reaction, which produces the diphosphate 5' end.

PTEN specifically catalyses the dephosphorylation of the 3` phosphate of the inositol ring in PIP3, resulting in the biphosphate product PIP2 (PtdIns(4,5)P2).

For example, methyl iodide catalyses the conversion of trimethylphosphite to the phosphonate ester dimethyl methylphosphonate:.

This enzyme catalyses the first step in ubiquinone biosynthesis in Escherichia coli and other Gram-negative bacteria.

YpkA also catalyses serine autophosporylation, so it may have regulatory functions in Yersinia or undermine host cell immune response signal cascades since YpkA is targeted to the cytoplasmic side of the host cell membrane.

These proteins are usually the transposase which catalyses the enzymatic reaction allowing the IS to move, and also one regulatory protein which either stimulates or inhibits the transposition activity.
