ENZYME entry: EC 3.4.21.100

Accepted Name
Sedolisin.
Alternative Name(s)
Pseudomonalisin.
Pseudomonapepsin.
Pseudomonas sp. pepstatin-insensitive carboxyl proteinase.
Sedolysin.
Reaction catalysed
Hydrolysis of the B chain of insulin at 13-Glu-|-Ala-14, 15-Leu-|-Tyr-16 and 25-Phe-|-Tyr-26 and angiotensin I at 4-Tyr-|-Ile-5. A good synthetic substrate is Lys-Pro-Ile-Glu-Phe-|-Phe(NO(2))-Arg-Leu
Comment(s)
  • An enzyme secreted by Pseudomonas sp. No. 101.
  • Optimum pH 4.
  • It is distinguished from EC 3.4.21.101 by its insensitivity to EPNP and from EC 3.4.23.31 by this property and by its unrelated amino- acid sequence.
  • Inhibited by tyrostatin, a peptide aldehyde.
  • Belongs to peptidase family S53.
  • Formerly EC 3.4.23.37.
