Serological relatedness of bacterial deoxyribonucleic acid polymerases.
A number of bacterial species have been surveyed for serological activities with antiserum to Escherichia coli B deoxyribonucleic acid (DNA) polymerase I (EC 2.7.7.7.). The degree of serological cross-reaction is taken as a measure of relatedness of both the enzyme molecules from various species and the bacterial species themselves. Extracts were assayed by complement fixation only after treatm...

MISSOURI The enzymatic synthesis of DNA1 in sufficient excess over the DNA used to prime the reaction21 a has enabled us to examine the chemical composition of the synthetic product. As has already been demonstrated, this DNA consists of deoxy-nucleotides Linked by typical 3'-5' phosphodiester bonds, and all four of the deoxy
متن کاملDeoxyribonucleic acid-deoxyribonucleic acid hybridization assay for replication origin deoxyribonucleic acid of Escherichia coli.
Deoxyribonucleic acid (DNA)-DNA hybridization on nitrocellulose filters can be used to assay for replication origin DNA from Escherichia coli if the DNA attached to the filters is enriched for the replication origin sequences. Such DNA can be readily isolated from very rapidly growing cells. When low amounts of this DNA were attached to filters, radioactively labeled DNA from the replication or...

Triostin antibiotics, which contain a cyclic peptide with a disulphide bridge, have been prepared by growing Streptomyces triostinicus in the presence of inorganic [3PS]sulphate. The labelled triostin A has been shown to behave in all respects similarly to the authentic natural product and to enable a much more sensitive radiochemical adaptation of the solvent-partition method for determining a...

The effects of the three antibiotics U-12,241, nogalamycin, and U-20,661 on (i) deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) synthesis in KB cell cultures and cell-free systems of bacterial and mammalian origin and on (ii) oxidative phosphorylation in rat liver mitochondria were compared. Nogalamycin and U-12,241 inhibited RNA synthesis more strongly than DNA synthesis in all test sys...
