Allantoinase - Wikipedia
WebIn enzymology, an allantoinase (EC 3.5.2.5) is an enzyme that catalyzes the chemical reaction (S)-allantoin + H 2 O allantoate. Thus, the two substrates of this enzyme are (S)-allantoin and H 2 O, whereas its product is allantoate.

WebAllantoinase, the enzyme catabolizing the further degradation of S-allantoin, resides in the endoplasmic reticulum (ER) in plants [8,32]. It is unclear how allantoin is translocated from the peroxisome into the ER.
Allantoin - Wikipedia
WebAllantoin is a chemical compound with formula C 4 H 6 N 4 O 3. It is also called 5-ureidohydantoin or glyoxyldiureide. [1] [2] It is a diureide of glyoxylic acid. Allantoin is a major metabolic intermediate in most organisms including animals, plants and bacteria.
