Protein data base profile characteris arylsulfatase asa hydrolase and a sulfatase. A hydrolase is an enzyme which hydrolyses a chemical bond. The general reaction can be shown as follows.
Group of hydrolaes are named as EC 3 in enzyme classification.
1. Function of sulfatases
Sulfatases are enzymes,which hydrolyse sulfate ester bonds of substrates. These are categorised as EC 3.1.6. in enzyme classifications. Most of the family members has shown to contain a highly conserved cystine residue and a bivalent metal binding site.
2. Functional site
MSA data revealed some conserved residues on the sequence. They were mapped on the three dimantional structure.
Highly conserved regions of the protein revealed in MSA are highlighted in blue, while ligands; Zn and Cl; are shown in green and grey respectively. However region of high conservation seems to be physically further from ligand binding sites. May be sudgessting that ligands only play a role in stabilizing the protein conformation, hense the active site; for the enzyme to perfprm its catalytic functions.
