Miscellaneousi

Miscellaneous

The two forms of this enzyme, I and II, show very similar activities, molecular masses, and compositions and differ only in their isoelectric points. As no evidence for two variants were in the cDNA library of PubMed:10082956, it is most likely that isoform I (PPAI) and isoform II (PPAII) are two forms of the same protein.
