3.1.3.9	glycoprotein	-	698186	
3.1.3.9	additional information	chemical modification of thiol groups belonging to proteins involved in the enzyme system by DTNB, NTCB and IAEDANS decrease the enzyme activity, the incubation with phosphate preventes the loss of activity, the addition of 2-mercaptoethanol allows a 50% restoration of the initial activity, however chemical modification of thiol groups by pHMPS, pHMB, AMSDS and NEM decrease the enzyme activity	649477	
3.1.3.9	side-chain modification	enzyme is active as a phosphoprotein, dephosphorylation leads to inactivation	134932
