<i>I. hospitalis</i> proteins enriched in the <i>N. equitans</i> sample.

The enrichment factor, φ, was calculated as the ratio of the abundance of an individual I. hospitalis protein (P) relative to the total I. hospitalis proteome (T) between the purified N. equitans (N) and the co-culture (I_N) sample (φ = [PN/TN]/[PI_N/TI_N]). Total proteome values used in the calculation are TN = 11878, TI_N = 75139.
