PROSITE documentation PDOC00836
TatD deoxyribonuclease family


Description

The Escherichia coli protein tatD is a cytoplasmic protein with magnesium-dependent DNase activity [1]. It is similar to a number of proteins in all three kingdoms of life, among which:

  • Yeast chromosome II hypothetical protein YBL055c.
  • Escherichia coli hypothetical protein ycfH and HI0454, the corresponding Haemophilus influenzae protein.
  • Escherichia coli hypothetical protein yjjV and HI0081, the corresponding Haemophilus influenzae protein.
  • Bacillus subtilis hypothetical protein yabD.
  • Haemophilus influenzae hypothetical protein HI1664.
  • Mycoplasma genitalium hypothetical protein MG009.

These are proteins of from 24 to 47 Kd which contain a number of conserved regions. They can be picked up in the database by the following patterns.
