Amino acid sequences of the A domains of PpaA1, CorA, HapA1, HapA2, and related enzymes were aligned with ClustalW [69]. Specificity code positions 5 and 6 are numbered according to the GrsA sequence [16]. The amino acid on position 5 and the substrate of the respective enzyme are highlighted in matching colors. Green: Val/Ile – phenylpyruvic acid (PP); cyan: Asn – 4-hydroxyphenylpyruvic acid (4-HPP); grey: Ile – phenylalanine (Phe)
