Enzyme Information
| 2.7.11.1 | 
							 Non-specific serine/threonine protein kinase. 
							based on mapping to UniProt P19525 		
							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 2.7.1.37 and EC 2.7.1.70. 
						 | 
					
| 2.7.10.2 | 
							 Non-specific protein-tyrosine kinase. 
							based on mapping to UniProt P19525 		
							ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. 
							-!- Unlike EC 2.7.10.1, 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 2.7.1.112.
