title: Cloning and sequence analysis of the human liver rhodanese: comparison with the bovine and chicken enzymes.
abstract: The cDNA for the human rhodanese (thiosulfate: cyanide sulfurtransferase, EC 2.8.1.1), a nuclearly encoded protein of the mitochondrial matrix, was isolated from a human fetal liver cDNA library. Nucleotide sequence revealed an open reading frame coding for a polypeptide of 295 amino acids, which presented a 57% and 58% identity with the bovine and avian rhodanese, respectively. The analysis of the 5'-ends of the coding region gave no evidence for the presence of a cleavable signal sequence as found in other mitochondrial proteins. A comparison with two available amino acid sequences (cow and chicken) showed that sequence similarity is not restricted to the alpha-helices and beta-structures motifs which are remarkably superimposable in the two halves of bovine rhodanese, but extends to adjacent regions.
