3.4.23.1	1	4.5	24 h, 20°C	36758	
3.4.23.1	2	-	at pH 2.0 and 14°C, isoform PG1-1 and PG2-2 are converted through intermediate forms into their respective pepsins. While the intermediate form of PG1-1 is rather stable, as the enzyme remained in that form for more than 60 min, the intermediate form of PG2-2 is converted to pepsin rapidly	753325	
3.4.23.1	2.1	4.5	the enzyme activity is stable at pH 2.1-4.5	754305	
3.4.23.1	2.2	5.9	45°C, pH 2.16: 7% loss of activity after 40 min, pH 5.93: 12% loss of activity after 40 min	36733	
3.4.23.1	3	10	pepsin A is completely inactivated at pH 3.0-10.0 at 37°C after 30 days, the enzyme is unstable at pH 7.0 and above (irreversible inhibition)	717394
