hPTH-(1-34) crystallizes as a slightly bent, long, helical dimer. The extended helical conformation of hPTH-(1-34) is the likely bioactive conformation. The N-terminal fragment 1-34 of<unk>  <unk>  has been crystallized and the structure has been refined to 0.9 Å resolution. helical dimer structure of hPTH-(1-34)
