1.11.2.1	35	50	at 35°C, there is some activity loss after 60 min but the enzyme remains mostly active even after longer incubations. The enzyme is mostly inactivated after 20-30 minute exposures to temperatures higher than 50°C. Conversely, the enzyme overall activity is minimally affected at 40°C and after 90 min the enzyme mostly loses activity	763786	
1.11.2.1	53	-	the enzyme shows 50% activity after 1 h at 53°C	741683	
1.11.2.1	56	-	mutant S61A/L79I/A252L of isoform UPO-I retains 50% of its activity after 10 min incubation at 56°C	763973	
1.11.2.1	61	-	isoform UPO-II retains 50% of its activity after 10 min incubation at 61°C	763973
