Description
An enzyme secreted by Pseudomonas sp. No. 101. Optimum pH is 4. It is distinguished from xanthomonapepsin by its insensitivity to EPNP and from scytalidopepsin B by this property and by its unrelated amino-acid sequence. Inhibited by tyrostatin, a peptide aldehyde. Type example of peptidase family S53.
Form
Liquid or lyophilized powder
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
Pseudomonas sp. pepstatin-insensitive carboxyl proteinase; pseudomonapepsin; pseudomonalisin; sedolysin
Reaction
Hydrolysis of the B chain of insulin at -Glu13┼Ala-, -Leu15┼Tyr- and -Phe25┼Tyr-, and angiotensin I at -Tyr4┼Ile-. A good synthetic substrate is Lys-Pro-Ile-Glu-Phe┼Phe(NO2)-Arg-Leu.
