In enzymology, a pantetheine hydrolase (EC 3.5.1.92) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are (R)-pantetheine and H2O, whereas its two products are (R)-pantothenate and 2-aminoethanethiol.
This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is (R)-pantetheine amidohydrolase. Other names in common use include pantetheinase, vanin, and vanin-1. This enzyme participates in pantothenate and CoA biosynthesis.
Kynureninase or L-Kynurenine hydrolase (KYNU) is a PLP dependent enzyme that catalyses the cleavage of kynurenine (Kyn) into anthranilic acid (Ant). It can also act on 3-hydroxykynurenine and some other (3-arylcarbonyl)-alanines. Humans express one kynureninase enzyme that is encoded by the KYNU gene located on chromosome 2.
