Figure 3From: The acid-tolerant L-arabinose isomerase from the mesophilic Shewanella sp. ANA-3 is highly active at low temperaturesShewanella sp. ANA-3 L -AI activity. (A): Effect of divalent metal ions. (B): Effect of various concentrations of Mn2+ (♦). "MD" indicates enzyme activity measured in a metal depleted solution. Activities at optimal metal ion concentrations were defined as 100%. Error bars represent the standard deviation from three independent experiments.Back to article page
