Annotation score:3 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Optimum pH is 5.5. Stable above pH 5.5.

Temperature dependencei

Optimum temperature is about 90 degrees Celsius. Highly thermostable. Retains 70% of its maximal activity after heating 1 hour at 90 degrees Celsius, but no decrease in activity was observed within the same time at 80 degrees Celsius.

<p>The checksum is a form of redundancy check that is calculated from the sequence.
