The interaction of skeletal muscle phosphofructokinase
with a variety of acidic proteins including calmodulin and
troponin C and with nucleic acids (RNA and DNA) is manifest
in a reversible, time-dependent loss of catalytic activity.
The inactivation is affected by a number of factors.
Substrates (fructose-6-phosphate and ATP), positive
effectors (fructose-2,6-bisphosphate,...
By using immobilized trypsin, I have been able to
prepare well-defined, stable trypsinized nucleosomes. The
difficulties of lacking of control in the extent of
trypsinization, which were encountered in previous studies
with the use of free trypsin, have been eliminated. The
nucleosomes and oligonucleosomes prepared by immobilized
trypsin are suitable...
Size and color are important visual quantity attributes of the fruit of strawberry (Fmgaria x ananassa Duch.). Strawberry cultivars produce fruit of a characteristic size and color, the later being the result of accumulation of particular anthocyanins. This research sought to determine the basis for genotypic differences in fruit size...
