IntEnz Enzyme Nomenclature


Accepted name:
Other names:
Pseudomonas sp. pepstatin-insensitive carboxyl proteinase
Systematic name:



An enzyme secreted by Pseudomonas sp. No. 101. Optimum pH is 4. It is distinguished from EC, xanthomonalisin, by its insensitivity to EPNP and from EC, scytalidopepsin B, by this property and by its unrelated amino-acid sequence. Inhibited by tyrostatin, a peptide aldehyde [2]. Type example of peptidase family S53.
