The complete intron-exon organization of the gene encoding a multifunctional mammalian fatty acid synthase has been elucidated, and specific exons have been assigned to coding sequences for the component domains of the protein. The rat gene is interrupted by 42 introns and the sequences bordering the splice-site junctions universally follow the GT/AG rule. However, of the 41 introns that interrupt the coding region of the gene, 23 split the reading frame in phase I, 14 split the reading frame in phase 0, and only 4 split the reading frame in phase II. Remarkably, 46% of the introns interrupt codons for glycine. With only one exception, boundaries between the constituent enzymes of the multifunctional polypeptide coincide with the location of introns in the gene. The significance of the predominance of phase I introns, the almost uniformly short length of the 42 introns and the overall small size of the gene, is discussed in relation to the evolution of multifunctional proteins.
