Primary structure of rat liver serine dehydratase deduced from the cDNA sequence.
The nucleotide sequence of serine dehydratase mRNA of rat liver has been determined from a recombinant cDNA clone, previously cloned in this laboratory, and from a recombinant cDNA clone screened from a primer-extended cDNA library. The sequence of 1322 nucleotides includes the entire protein coding region and noncoding regions on the 3'- and 5'-sides. The deduced polypeptide consists of 327 amino acid residues with a calculated molecular mass of 34,462 Da. Comparison of the amino acid sequences of the serine dehydratase polypeptide with those of biosynthetic threonine dehydratase of yeast and biodegradative threonine dehydratase of E. coli revealed various extents of homology. A heptapeptide sequence, Gly-Ser-Phe-Lys-Ile-Arg-Gly, which is the pyridoxal-binding site in the yeast and E. coli threonine dehydratases was found as a highly conserved sequence.
