3bsqA Discussion

   Multiple sequence alighment revealed some conserved residues throughput the whole sulfatase family. Previous experiemnts describe a set of crutial residues for the sulfatase function of an enzyme. A histidine residue (H)  and two or more sequential arganine residues (R) are known to be essential, and also characteristic of the N-terminal active site of sulfatases. Our MSA resultaes a a set of residues conserves in the N-terminus, along with a H and one R residue.
