Hepatic poly(A+) RNA from rats induced for stearyl-CoA desaturase was used for primer-extension of cDNA coding for stearyl-CoA desaturase. Previously, Northern blot analysis showed that translatable desaturase mRNA is 4,900 nucleotides in length (Thiede, M. A., and Strittmatter, P. (1985) J. Biol. Chem. 260, 14459-14463). Six overlapping cDNAs, ranging from 850 to 1450 bases, were used to compile the 4,689-nucleotide sequence. The cDNA includes a 1,074-base open reading frame coding for 358 amino acids, corresponding to a molecular mass of 41,400 daltons. Positive identification of this open reading frame was accomplished by matching the amino acid sequence of both amino-terminal and cyanogen bromide peptides of the purified enzyme with regions of the sequence deduced from the cDNA. Amino acid composition data from the cDNA compares well with that from the desaturase. The protein contains 62% hydrophobic amino acids. An interesting feature of this mRNA is the 3,500-base 3' noncoding region, which has been localized on a single 3' exon by Southern blot analysis.
