Asp, XaaGlu and Xaacysteic acid bonds
Reaction: Cleavage of XaaAsp, XaaGlu and Xaacysteic acid bonds
Other names: endoproteinase Asp-N; peptidyl-Asp metalloproteinase
Comments: A metalloenzyme isolated from Pseudomonas fragi. Useful in protein sequencing applications because of its limited specificity. In peptidase family M72.
