Importance of the propeptide sequence of human preproparathyroid hormone for signal sequence function.
The function of amino-terminal pro-specific peptides (propeptides), sequences often found on intermediate precursor forms of secreted proteins, is poorly understood. Human preproparathyroid hormone (prepro-PTH), a precursor protein containing such a propeptide, is initially synthesized as a precursor containing a 25-amino acid signal sequence, a 6-amino acid propeptide, and the 84-amino acid ma...
متن کاملThe N-terminal amino-acid sequence of bovine proparathyroid hormone.
Proparathyroid hormone (calcemic fraction-A) is a biosynthetic precursor of parathyroid hormone in bovine glands. Limited amounts of the isolated prohormone have been obtained for the purpose of initial structural studies. The results of automated sequence analysis on two separate preparations indicate that the N-terminal region of the prohormone consists of the sequence Lys-Ser-Val-Lys-Lys-Arg...
متن کاملHuman parathyroid hormone: amino-acid sequence of the amino-terminal residues 1-34.
Human parathyroid hormone has been isolated in highly purified form from human parathyroid adenomas. The primary sequence of the amino-terminal 34 residues of the human hormone was obtained by automated degradation with a Beckman Sequencer. The phenylthiohydantoin amino acids were identified by gas chromatography and mass spectrometry. The first 34 residues of human parathyroid hormone differ f...
متن کاملThe amino-terminal sequence of porcine pepsinogen.
Amino acid sequence studies were performed on (a) peptides obtained from tryptic hydrolysates of succinyl pepsinogen and (b) those isolated from a peptide mixture formed when pepsinogen is activated to pepsin. These peptides taken together with tryptic peptides obtained from reduced carboxymethylated pepsinogen establish the complete sequence of 41 residues at the NH&erminal end of the single p...
متن کاملAmino acid composition and amino-terminal sequence of yeast enolase.
The recent finding (1, 2) that part of the enolase molecule can be removed by digestion with leucine aminopeptidase or carboxypeptidase without change in enzymic activity has prompted a detailed study of the relation between structure and activity in this enzyme. As a basis for such investigations it is necessary to have a knowledge of the principal features of enolase structure; the amino acid...
