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 11 records (11 values) from this paper: dihydroneopterin aldolase (FolB), dihydroneopterin-triphosphate epimerase (FolX) from Escherichia coli, Haemophilus influenzae.
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.
