FunFam 10206: Xanthomonalisin

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Sedolisin. [EC: 3.4.21.100]
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.
  • 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.

Xanthomonalisin. [EC: 3.4.21.101]
Cleavage of casein.
  • Secreted by the bacterium Xanthomonas sp.
  • Belongs to peptidase family S53.
  • Formerly EC 3.4.23.33.
