In amphibian skin secretions, a peptidylprolyl cis/trans isomerase activity was detected. A Xenopus laevis skin cDNA coding for this protein was cloned, sequenced and over-expressed in Escherichia coli. The primary structure of the protein shows extensive similarity with members of the cyclophilin A family. Catalytic parameters of the recombinant protein are similar to those of the human enzyme. The...
The structure of a gene coding for bombinin-like peptides (BLP) in Bombina orientalis was determined. It comprises two exons separated by a 1337 bp intron. Exon 1 codes for the signal peptide, while exon 2 contains the genetic information for BLP-7 and a bombinin H-type peptide (GH-2). The promoter region contains putative recognition sites for nuclear factors, such as NF-IL6 and NF-κB. The analysis...
