To construct a mutant deficient in Pi and organic Pi transport, three organic Pi transporters (glpT, ugpB, and uhpT) were disrupted in addition to four Pi transporters (pitA, pitB, phnCDE, and pstSCAB 57.
Five prominent TI isoforms (TI-1 to TI-5) corresponding to 1-, 2-, 3- and 4-IRD were identified in uninduced leaves, in the pI range of 5 to 7. TI-6 (1-IRD) isoform which has major basic shift in pI compared to TI-1, was present in all the three types of induced tissues.
Sequence alignments of IC3-C58 with S100B binding sequences from p53, NDR kinase, and TRTK-12 showed there are no clear sequence similarities in any of these peptides other than a basic pI and several hydrophobic residues in the sequences.
These modified GAPDHs had higher molecular mass and more basic PI, and were present in the nucleus of activated T cells.
Another two related secreted peptides, sharing a basic pI and predicted mass near four kDa, were deduced from three ESTs found in the salivary gland library.
Indeed, a problem occurs when analysing proteins with a basic pI and high off rates.
Furthermore, 2-DE separation and western blotting revealed that the NGAL treatment decreases protein spots with basic pI and increases protein spots with acidic pI.
Figure 5B shows the matreshkaX amino acid sequence, which like Alex is basic (predicted pI 12.9) and enriched in proline residues (~3-fold more than average).
High level is defined as pI variation from acid in one or two organisms and basic in the other, and viceversa.
Xyn2 has a basic pI (9.0) and a wider pH range.
