Table S1 - Thermostable DNA Polymerase from a Viral Metagenome Is a Potent RT-PCR Enzyme

Exonuclease Assay. The indicated number of units of enzyme were incubated with [33P]-labeled PCR product for 10 minutes at 70°C as described in methods. Shown are the percent counts released with background (water-only control) subtracted. Not detected is indicated when counts are not significantly above background counts, i.e. (DOC)外切核酸酶实验（Exonuclease Assay）：按照实验方法所述，将指定活性单位的酶与[33P]标记的聚合酶链式反应（Polymerase Chain Reaction, PCR）产物在70℃条件下孵育10分钟。所得结果为扣除背景（仅水对照）后的释放计数百分比。当计数结果未显著高于背景计数时，标注为「未检出」，即（DOC）。
