Abstract

Overlapping cloned cDNAs representing the entire sequence of the rat fatty acid synthase mRNA have been isolated from a cDNA library and sequenced. Authenticity of the cDNA clones was supported by hybridization to fatty acid synthase mRNA and by amino-terminal sequencing of 39 fatty acid synthase CNBr fragments. The full-length fatty acid synthase mRNA is 9156 nucleotides long and includes an 84-nucleotide 5' noncoding region, a 7515-nucleotide coding sequence, and a 1537-nucleotide 3' noncoding region; a second mRNA species containing a shortened 3' noncoding sequence is also transcribed in the rat. The encoded fatty acid synthase subunit contains 2505 amino acids and has a molecular weight of 272,340. Active sites and substrate binding sites were located within the sequence, thus establishing the order of domains on the multifunctional animal fatty acid synthase as condensing enzyme-transferase-dehydrase-enoyl reductase-ketoreductase-acyl carrier protein-thioesterase.
