Figure 4. GLC analysis of FAME from recombinant yeast expressing IgD4.
Recombinant yeasts expressing IgD4 or vector alone were grown in the presence of 50 μM of the n–6 PUFA, ADA (22:4n–6) or the n–3 PUFA, ω3-DPA (22:5n–3). The corresponding n–6 product, 22:5n–6, and the n–3 product, DHA (22:6n–3), formed by the Δ4-desaturase activity of IgD4, are indicated by arrows. The x-axis represents retention time (min) and y-axis represents degree of response.
