Fig. 1From: The codon-optimized Δ6-desaturase gene of Pythium sp. as an empowering tool for engineering n3/n6 polyunsaturated fatty acid biosynthesisTopology model of PyDES6. Enzyme topology was predicted based on TMHMM and Phobius programs. The cylinders represent transmembrane regions of the enzyme, Cytb 5 indicates the N-terminal cytochrom b 5 domain, and three histidine-rich motifs are represented by H1, H2 and H3Back to article page
