The name of this superfamily has been modified since the most recent official CATH+ release (v4_2_0). At the point of the last release, this superfamily was named:

Transferase(Phosphotransferase) domain 1

FunFam 78758: Protein-tyrosine kinase HTK98, variant

There are 4 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
Non-specific protein-tyrosine kinase. [EC:]
ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
  • Unlike EC, this protein-tyrosine kinase does not have a transmembrane domain.
  • In the human genome, 32 non-specific protein-tyrosine kinases have been identified and these can be divided into 10 families.
  • Formerly EC

Receptor protein-tyrosine kinase. [EC:]
ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
  • The receptor protein-tyrosine kinases, which can be defined as having a transmembrane domain, are a large and diverse multigene family found only in metazoans.
  • In the human genome, 58 receptor-type protein-tyrosine kinases have been identified and these are distributed into 20 subfamilies.

Chitinase. [EC:]
Random endo-hydrolysis of N-acetyl-beta-D-glucosaminide (1->4)-beta- linkages in chitin and chitodextrins.
  • The enzyme binds to chitin and randomly cleaves glycosidic linkages in chitin and chitodextrins in a non-processive mode, generating chitooligosaccharides and free ends on which exo-chitinases and exo- chitodextrinases can act.
  • Activity is greatly stimulated in the presence of EC, which attacks the crystalline structure of chitin and makes the polymer more accesible to the chitinase.
  • Cf. EC

Non-specific serine/threonine protein kinase. [EC:]
ATP + a protein = ADP + a phosphoprotein.
  • This is a heterogeneous group of serine/threonine protein kinases that do not have an activating compound and are either non-specific or their specificity has not been analyzed to date.
  • Formerly EC and EC
