Analysis of PME isoforms expressed in Arabidopsis pollen
The deduced amino acid sequences of pollen-expressed PME isoforms are analyzed for the presence of a pro-region. The pI and molecular mass were calculated based on a prediction of the mature PME protein. The expression data of the PME genes are taken from Pina et al. (2005).
