Other claims from this paper (6)
- Observation Both the alpha and beta subunits of PPi-PFK were identified in the sugar cane EST database using Citrus paradisi sequences.
- Observation The deduced amino acid sequence of the sugar cane alpha subunit showed 76% similarity to the C. paradisi alpha subunit.
- Observation The deduced amino acid sequence of the sugar cane beta subunit showed 80% similarity to the C. paradisi beta subunit.
- Observation The alpha and beta subunits are distinct subunits found at different concentrations in several sugar cane tissues.
- Observation These residues are tightly conserved in all members of the protein family.
- Observation There appear to be catalytic residues on the b subunit of the pyrophosphate-dependent enzyme.
