Accepted name: 5-phospho-D-xylono-1,4-lactonase
Reaction: (1) D-xylono-1,4-lactone 5-phosphate + H2O = 5-phospho-D-xylonate
(2) L-arabino-1,4-lactone 5-phosphate + H2O = 5-phospho-L-arabinate
Systematic name: 5-phospho-D-xylono-1,4-lactone hydrolase
Comments: The enzyme, characterized from Mycoplasma spp., contains a binuclear metal center with two zinc cations. The enzyme is specific for the phosphorylated forms, and is unable to hydrolyse non-phosphorylated 1,4-lactones.
