3.4.23.18	2.5	6	fairly stable	668812	
3.4.23.18	2.5	6	the enzyme is stable in the pH range of 2.5-6.0, maintaining more than 80% of its activity after 1 h of incubation. Enzymatic activity is lost after incubation at pH 10.0	753450	
3.4.23.18	2.6	5	stable in this range	30563	
3.4.23.18	3	6	stable in this range, complete inactivation below 2 and above 7	30575	
3.4.23.18	4	-	most stable at	30564	
3.4.23.18	4.9	-	most stable at	30562	
3.4.23.18	5	8	the protease is relatively stable at pH 5.0, except in buffer containing sodium laurylbenzenesulfonic acid. However, at pH 8.0, whether in the absence or presence of reagents for 1 h, it loses almost all activity	754494	
3.4.23.18	6	7	above pH 7 denaturation and inactivation	30564	
3.4.23.18	8	12	the protease demonstrates excellent stability at pH range 8.0-12.0 for 30 min. The enzyme remains unaltered at pH 11.0 and 12.0 for 24 h at 28°C and a slight decrease in relative activity is seen at pH 10.0 after 24 h	752341
