IntEnz Enzyme Nomenclature


Accepted name:
allantoate deiminase
Other name:
allantoate amidohydrolase
Systematic name:
allantoate amidinohydrolase (decarboxylating)




This enzyme is part of the ureide pathway, which permits certain organisms to recycle the nitrogen in purine compounds. This enzyme, which liberates ammonia from allantoate, is present in plants and bacteria. In plants it is localized in the endoplasmic reticulum. Requires manganese.
