Figure 5.

Arginase enzyme activity of H99, ure1Δ and ure1Δ::URE1 strains of C. neoformans exposed to BHI and nutrient-limited (NL) media at 26 and 37°C. Enzyme activity is expressed as the nmol of urea produced from l-arginine per µg of protein. Bars represent the average of at least three biological replicates and error bars depict the standard error of the mean. Different letters indicate statistically significant differences (P < 0.05) and prime lettering indicates comparisons within the same temperature treatment.
