Figure 3From: Heterologous expression of leader-less pga gene in Pichia pastoris: intracellular production of prokaryotic enzymeComparison of substrate specificities of PGA Ec and hPGA Ec . Relative activities (%) of the purified PGAs with different substrates are shown. The activities of both PGAs measured with penicillin G as reaction substrate were taken as 100%. Three parallel measurements were performed with the same enzyme sample.Back to article page
