Fatty acid biosynthesis pathway reconstructed based on the de novo assembly and annotation of D. tertiolecta transcriptome. Identified enzymes are shown in boxes and include: ACC, acetyl-CoA carboxylase (EC:; MAT, malonyl-CoA ACP transacylase (EC:; KAS, beta-ketoacyl-ACP synthase (KAS I, EC:; KASII, EC:; KAS III, EC:; KAR, beta-ketoacyl-ACP reductase (EC:; HAD, beta-hydroxyacyl-ACP dehydrase (EC: 4.2.1.-); EAR, enoyl-ACP reductase (EC:; AAD, acyl-ACP desaturase (EC:; OAH, oleoyl-ACP hydrolase (EC:; FatA, Acyl-ACP thioesterase A (EC: 3.1.2.-); Δ12D, Δ126)-desaturase (EC:; Δ15D, and Δ153)-desaturase (EC: 1.4.19.-). The fatty acid biosynthesis pathway in D. tertiolecta produces saturated, C16:0 (palmitic acid) and C18:0 (stearic acid), and unsaturated fatty acids C18:1 (9) (oleic acid), C18:2 (9,12) (linoleic acid), and C18:3(9,12,15) (α-linolenic acid). Key enzymes are shown with an asterisk next to the boxes.
