The peptide A569-Y582 of the porcine estradiol receptor containing the missing sequence T570-M581 (1) was isolated and sequenced. The 4 seryl- and 2 threonyl-PTH amino acids were recovered in normal yields, excluding their posttranslational modification and reconfirming the absence of O-glycosylation and O-phosphorylation in H267-I595.
