Figure 4From: Prokaryotic aminopeptidase activity along a continuous salinity gradient in a hypersaline coastal lagoon (the Coorong, South Australia)Aminopeptidase activity along the salinity gradient. (A) maximum enzymatic velocity, V max (μM h-1), and (B) affinity with the substrate, K m (μM) from S1 to S4. Total enzymatic and free enzymatic activities are shown in black and grey, respectively. The error bars represent the standard deviations.Back to article page
