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 23 records (23 values) from this paper: KSTD1 (3-ketosteroid Δ1-dehydrogenase isoenzyme 1), KSTD2 (3-ketosteroid Δ1-dehydrogenase isoenzyme 2), KSTD3 (3-keto-5α-steroid Δ1-dehydrogenase) and 1 more from Rhodococcus erythropolis, Mycobacterium tuberculosis.

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.
