The paper itself is not on this site: read it at the publisher. This page lists only the values CatLog read from it.

CatLog read 8 records (24 values) from this paper: phytase (PhyA) from Aspergillus niger.

Read from the paper by an AI model and checked against the paper by a second, separate AI run; code converted the units. Values are in CatLog's units; each record opens in Browse with the line the paper prints and the checks.
