Figure 2From: Characterization of oxylipins and dioxygenase genes in the asexual fungus Aspergillus nigerAmino acid alignment of the predicted proximal His domain in A. niger PpoA, PpoC and PpoD to A. nidulans PpoA, PpoB and PpoC. Identical amino acids are marked with asterisks; similar amino acids are marked with colons. The proximal His and the Tyr residue important for catalysis in PGS are marked with ○ and ● respectively. Deviating amino acids (Phe instead of Trp, and Gln instead of Lys), in A. niger PpoD are indicated in grey.Back to article page
