Table 2. Kinetic parameters of PL1A, PL1B and PL9 with Polygalacturonic Acid (PGA) from citrus.

Enzyme Substrate Kcat (min−1) Km (mM) Kcat/Km (mM−1 min−1)
PL1A PGA (citrus) 1.3±0.03 0.0313±0.0005 41±0.23
PL1B PGA (citrus) 1.76±0.05 0.0286±0.0002 62±0.43
PL9 PGA (citrus) 1.32±0.05 0.0378±0.0004 35±0.4

One unit of enzymatic activity (U) was defined as the amount of enzyme in mg that produces 1 mmol/L of unsaturated product per minute.
