Abstract
- The amino acid sequence of a novel tissueand phasespecific nuclear protein (SNP) has been determined, after purification from the nuclei of the oviduct of the lizard Podarcis sicula Raf. during the reproductive period of the seasonal growth. SNP has a pI of 9.0 and contains 81 amino acid residues with a molecular weight of 9211.88 ± 0.09. It shows a bipartite organization as the first 40 amino acids contain all 8 cysteinyl residues, while the last 41 amino acids contain 16 prolyl residues. Two more components have also been identified and characterized, with the first 79 amino acids matching SNP and missing one or two residues at the Cterminus. They have thus been named [des(Ala[81]) SNP1] and [des(Lys[80]Ala[81]) SNP2], respectively. The molecular weights are 9140.21 ± 0.83 for [des(Ala[81]) SNP1] and 9011 ± 0.09 for [des(Lys[80]Ala[81]) SNP2].
