Thiocyanate hydrolase

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in nitriles. The systematic name of this enzyme class is thiocyanate aminohydrolase.

Structural studies

As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes 2DD4, 2DD5, 2DXB, and 2DXC.
