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 (47 values) from this paper: CTX-M-25, CTX-M-26 from Escherichia coli, Klebsiella pneumoniae.

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 1 kcat/Km value marked “calc.” from kcat and Km; no printed kcat/Km was read for that record.
