Abstract: | A partial cDNA for rabbit muscle phosphofructokinase (Rm-PFK) has been cloned and sequenced. The nucleotide sequence of the cDNA agrees with the previously determined Rm-PFK genomic sequence. In addition, the amino acid sequence deduced from the cDNA is nearly identical to the Rm-PFK sequence previously determined by peptide analysis. A significant degree of homology exists when the amino acid sequence of Rm-PFK is compared with the sequences of Bacillus stearothermophilus PFK or Escherichia coli PFK-1. The cloning and sequencing of the PFK cDNA fragment represents significant progress toward the long term goal of using site-specific mutagenesis to investigate the structure-function relationships in this allosteric enzyme. |
