Pantothenase

In enzymology, a pantothenase (EC 3.5.1.22) is an enzyme that catalyzes the chemical reaction

(R)-pantothenate + H₂O ${\displaystyle \rightleftharpoons }$ (R)-pantoate + beta-alanine

Thus, the two substrates of this enzyme are (R)-pantothenate and H₂O, whereas its two products are (R)-pantoate and beta-alanine.

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)-pantothenate amidohydrolase. Other names in common use include pantothenate hydrolase, and pantothenate amidohydrolase. This enzyme participates in pantothenate and coa biosynthesis.
