Isoelectric points (pI) of the ERGp orthologs in C. elegans and D. melanogaster.

The mean pI values (and standard deviations –std) of the orthologous proteins in cholesterol prototrophs are shown for comparison. “pI (w/o)” stands for means +/− std calculated without taking into account the orthologs in C. elegans and D. melanogaster while “pI (w)” stands for means +/− std calculated including the orthologs in C. elegans and D. melanogaster. “n” is the number of orthologs in cholesterol prototrophs used to calculate the means.
