3.4.23.4	2	3.8	-	667435	
3.4.23.4	2	6	under incubation at 37°C for 24 and 48 h, loss of activity at pH 3.5 and pH 7.0, trangenic chymosin and recombinant chymosin are inactivated slightly faster than the native enzyme	667763	
3.4.23.4	2	6.5	crystalline chymosin exhibits optimum stability at pH between 5.3 and 6.3, the enzyme is moderately stable at pH 2.0, but the enzyme is unstable at pH around 3.5 and above 6.5, clotting activity is not observed at pH 7.0	708236	
3.4.23.4	2	8	the enzyme retains 80% of activity within pH 2.0-8.0	731169	
3.4.23.4	2.5	6.5	the recombinant enzyme is highly active and stable over a wide pH range (from 2.5 to 6.0) at 20°C for 8 h. Relative clotting activity declines when the recombinant chymosin is kept at a pH value above 6.0. No detectable clotting activity at pH 6.5	732866	
3.4.23.4	3.5	-	rapid loss of activity	36882	
3.4.23.4	3.5	7	the enzyme remains stable (100% activity) for 1 h at pH 3.5-7.0. At pH 7.5 and 8.0, the activity drops to about 40% and 20%, respectively. The enzyme is inactive after 1 h at pH 9.0	755314	
3.4.23.4	5.3	6.3	highest stability	36882	
3.4.23.4	7	-	rapid loss of activity above	36882
