NOTE: In each cell, the first value is kcat (s-1), the second value is Km (µM) and the third value is kcat/Km (s-1·mM-1). When two values are present on the same line, the first correspond to V0 and the second to Vss.

Abbreviations: ND - not determinable; NH – no hydrolysis detected; NA – not available.

Statistics (number of kinetics): Overall (47); class A (21); subclass B1 (3); subclass B2 (0); subclass B3 (4); class C (0); class D (19).
