Functioni

Catalytic activityi

A phosphate monoester + H2O = an alcohol + phosphate.1 Publication

Enzyme regulationi

Activated slightly by Co2+, Ca2+ and Mg2+. Strongly inhibited by NaF, Fe3+ and Al3+, less so by tartrate, Cu2+ and Hg+. Not affected by EDTA, Fe2+ and Zn2+.1 Publication

Kineticsi

  1. KM=248 µM for para-nitrophenylphosphate (p-NPP)1 Publication
  1. Vmax=9 nM/min/mg enzyme1 Publication

pH dependencei

Optimum pH is 4.6. Activity decreases sharply with decreases and increases in pH and is absent at pH 8.0. When pre-incubated at different pH levels, activity is stable between pH 4 and 9.1 Publication

Temperature dependencei

Optimum temperature is 50 degrees Celsius. Activity decreases sharply with decreases and increases in temperature. When pre-incubated at different temperatures, activity is stable between 20 and 50 degrees Celsius.1 Publication

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.
