Abstract

We have isolated the gene for the human liver-type phosphofructokinase, from upstream to the 5′ mRNA terminus to beyond the polyadenylation site. The gene is at least 28 kb long and is divided into 22 exons; it contains conventional splice-junction sequences and one polyadenylation signal. Exons and introns are quite rich in G and C residues; some 60% of all nucleotides are either G or C. Five possible sites of polymorphism have been found. The gene structure reveals no signs of internal similarities despite protein sequence evidence which suggests that the PFK molecule is divided into two similar halves. The structure and organization of the human liver-type PFK gene are shown to be extremely similar to those of the rabbit muscle-type PFK.
