HtrA2 peptidase (EC 3.4.21.108 high temperature requirement protein A2 HtrA2 Omi stress-regulated endoprotease serine proteinase OMI OMI/HtrA2 protease HtrA2/Omi Omi/HtrA2) is an enzyme. This enzyme catalyses the following chemical reaction Cleavage of non-polar aliphatic amino-acids at the P1 position with a preference for Val Ile and Met. This enzyme is upregulated in mammalian cells in response to stress induced by heat shock and tunicamycin treatment.
