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 16 records (48 values) from this paper: cytosolic glutamine synthetase GLN1;3, cytosolic glutamine synthetase GLN1;4 from Arabidopsis thaliana.
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.
