PROSITE documentation PDOC00973Tpx family signature
Description
Escherichia coli protein tpx [1] is an antioxidant protein with a thiol peroxidase activity. It is a small protein of 18 Kd whose sequence is well conserved in other bacterial species.
As a signature pattern we selected the best conserved region which is located in the central part of these proteins. This region contains one of two conserved cysteines.
