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 6 records (10 values) from this paper: O-acetylserine sulfhydrylase (OASS) from Aeropyrum pernix.
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 4 kcat/Km values marked “calc.” from kcat and Km; no printed kcat/Km was read for those records.
