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 88 records (249 values) from this paper: tryptophan synthase alpha2.beta2 complex, tryptophan synthase alpha subunit (alone, without beta2 subunit), tryptophan synthase beta2 subunit (alone, without alpha subunit) from Escherichia coli.

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. CatLog calculated the 2 kcat/Km values marked “calc.” from kcat and Km; no printed kcat/Km was read for those records.
