Chains	Enzyme Name	Description	Catalytic Residues
A	3'(2'),5'-bisphosphate nucleotidase M-CSA #904	Catalyses the removal of the 3'-phosphate from adenosine 5'-phosphosulfate to reform AMP. This reaction helps drive the sulfur incorporation cycle for pathways such as methionine biosynthesis. Sensitivity of this essential enzyme to sodium and other metal ions results is responsible for characterisation of this enzyme as a salt tolerance protein [PMID:10205895]. Some members of this family are active also as inositol 1-monophosphatase.
