Studies on pituitary lactogenic hormone. The primary structure of the porcine hormone.
The complete amino acid sequence of porcine lactogenic hormone has been elucidated. It consists of 199 amino acid residues with three disulfide bridges formed by residues 4-11, 58-174, and 191-199. The two tryptophan residues are in positions 91 and 150. A high degree of homology exists between the known structure of ovine prolactin and the porcine lactogenic hormone. This led to a re-examination of residues 82-90 in the ovine prolactin structure, where an extra leucine was found in position 88.
