^aGenes are termed as the D. melanogaster orthologs, PPP classification is given according to Cohen [65].

^bThe revised protein sequence can be found at http://www.medchem.dote.hu/hu/node/1127.

^cThe two Nvit_CanA1 sequences have been arbitrarily differentiated as A and B.

PPP genes that contain no introns in their coding regions are underlined. The two types of PPP3 are separated by a broken line.
