Peptidase Do
Peptidase Do (EC 3.4.21.107, DegP, DegP protease, HtrA, high temperature requirement protease A, HrtA heat shock protein, protease Do, Do protease) is an enzyme.[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction
- Acts on substrates that are at least partially unfolded. The cleavage site P1 residue is normally between a pair of hydrophobic residues, such as Val-Val
