RESUMO
The primary structure of prothymosin alpha from rat thymus, containing 113 amino acid residues, is reported as follows: (formula; see text) The sequence of the first 28 amino acids at the NH2 terminus is identical to that of calf thymosin alpha 1. The dicarboxylic amino acids, which account for nearly half of the total residues in prothymosin alpha, are largely clustered in the central portion of the polypeptide chain. The polypeptide contains no aromatic or sulfur-containing amino acids. A computer analysis of the three-dimensional structure based on the primary sequence suggests that the molecule is composed of at least five alpha-helical regions interrupted by one short extended chain and three short random coils.
