Other name(s): UGlyAH; UGHY; ylbA (gene name)

Systematic name: (S)-ureidoglycine aminohydrolase

Comments: Binds Mn2+. This enzyme, found in plants and bacteria, is part of the ureide pathway, which enables the recycling of the nitrogen in purine compounds. In plants it is localized in the endoplasmic reticulum.
