1. 1. We have recently established from sequence analysis that rat liver fructose-1,6-bisphosphatase contains a 24-26 residue extension beyond the COOH-terminal amino acid of other mammalian fructose-1,6-bisphosphatases that results in an increased subunit molecular weight (Rittenhouse et al. (1983) J. Biol. Chem. 258, 7648-7652). 2. 2. In the present work the distribution of the COOH-terminal extension of fructose-1,6-bisphosphatases was tested by subunit molecular weight analysis of the enzyme immunoprecipitated from liver extracts. 3. 3. Of all rodent species tested, including several Muridae other than Rattus; only the enzyme from animals of the genus Rattus was found to have the extension. Further studies on the distribution of the enzyme extension could provide a simple tool to study the phylogeny of the genus Rattus.
