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 18 records (27 values) from this paper: hypoxanthine-guanine-xanthine phosphoribosyltransferase (HGXPRTase), guanine phosphoribosyltransferase (GPRTase) from Tritrichomonas foetus, Giardia lamblia.

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 9 kcat/Km values marked “calc.” from kcat and Km; no printed kcat/Km was read for those records.
