The sequences of the 119 amino acids of bovine and porcine luteinizing hormone β-subunits were determined, 17 amino acid replacements being observed between these species. Variability in the primary structure was observed for porcine β-subunit, in that position 10 is occupied by both arginyl and glutamyl residues. No free amino terminal residue was detected for both porcine and bovine β-polypeptide chains and both exhibited carboxy-terminal heterogeneity. The homology of the β-subunits of luteinizing hormone from various species and the β-subunit of the bovine thyroid-stimulating hormone is discussed as the subunit of both hormones can combine with a similar α-subunit.
