Central Oregon is the primary U.S. hybrid carrot seed production area, supplying seed to the domestic fresh market carrot industry. Approximately 85 percent of the hybrid carrot seed planted in the United States is grown
in Jefferson and adjoining counties. The Madras and Culver areas support most of the carrot...
The ability to faithfully replicate DNA is dependent upon the maintenance
and regulation of its precursors, the deoxyribonucleoside triphosphates.
Enzymes encoded by the bacteriophage T4 have been widely used as models
of biochemical processes. A body of evidence supports the concept that the
bacteriophage T4 enzymes involved in deoxyribonucleotide biosynthesis...
Many ecologists and environmental scientists witnessing the scale of current environmental change are becoming increasingly alarmed about how humanity is pushing the boundaries of the Earth’s systems beyond sustainable levels. The world urgently needs global society to redirect itself toward a more sustainable future: one that moves intergenerational equity and...
Investigators have been studying an aggregate
containing enzymes of deoxyribonucleoside triphosphate
biosynthesis in T4-phage infected bacteria. They suggest
that it behaves as an organized complex, efficiently
channeling DNA precursors to the replication apparatus.
Previous work has suggested that about 10 enzyme
activities remain associated through several fractionation
steps. This multi-enzyme...
With respect to a multienzyme complex of deoxyribonucleoside triphosphate (dNTP) synthesis somehow juxtaposed with DNA replication sites, our laboratory has demonstrated the existence of a multienzyme complex in T4-infected E. coli, named the T4 dNTP synthetase complex, but the idea of direct linkage of dNTP synthesis to DNA replication and...
