Amino 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.
