Fig. 5. Oxidoreductase identification in marine metagenomes.

a Proportion of oxidoreductase sequences (y-axis) predicted by the oxidoreductase classifier in surface (n = 7), mesopelagic (n = 4), and oxygen minimum zone (OMZ, n = 4) depths. Box shows median and interquartile range, whiskers extend to minima and maxima of range, and diamonds indicate outliers defined as 1.5x the interquartile range. b Correlation between the proportion of oxidoreductases and absolute degrees latitude in surface metagenomes of the oxidoreductase metagenome set (R² = 0.79, P = 0.04, n = 15). 95% confidence interval shown, estimated by bootstrapping with 1000 resamples. c Proportion of sequences predicted as oxidoreductases, not oxidoreductases, or left unannotated across the oxidoreductase classifier, MG-RAST, and mi-faser tools.
