  1. Vmax=51.6 µmol/min/mg enzyme with pNPP as substrate (at 76 degrees Celsius)

pH dependencei

Optimum pH is 5.5-6.2.

Temperature dependencei

Optimum temperature is 80 degrees Celsius. Active up to 95 degrees Celsius.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
