Effect of T4 modification of host valyl-tRNA synthetase on enzyme action in vivo
(Elsevier, 1975-10)
It has previously been found that bacteriophage T4 modifies the valyl-tRNA synthetase of its host; in this work we have examined the effects of this modification on the action of the enzyme in vivo. For this purpose we ...
Methylation of plasmacytoma c-myc genes
(Elsevier, 1985)
The chromosomal translocation associated with many tumors of immunoglobulin-producing cells frequently results in the joining of the immunoglobulin heavy-chain locus and the c-myc oncogene. This translocation of c-myc has ...
[lambda]imm[lambda][middle dot]434: A phage with a hybrid immunity region
(Elsevier, 1973-11)
The genomes of coliphages [lambda] and [lambda]imm434 are identical with the exception of the immunity region, which codes for the respective repressors and corresponding operators. Although previous genetic studies failed ...
A comparison of variant theories of intact biochemical systems. II. flux-oriented and metabolic control theories
(Elsevier, 1989-06)
In the past two decades, several theories, all ultimately based upon the same power-law formalism, have been proposed to relate the behavior of intact biochemical system to the properties of their underlying determinants. ...
Functional Analysis of MycE and MycF, Two O -Methyltransferases Involved in the Biosynthesis of Mycinamicin Macrolide Antibiotics
(WILEY-VCH Verlag, 2009-05-25)
Mg motors : We characterized the in vitro function of MycE and MycF, two O -methyltransferases involved in the biosynthesis of mycinamicin antibiotics. Each enzyme was confirmed to be an S -adenosyl- L -methionine ...
A phase variation event that activates conjugation functions encoded by the Enterococcus faecalis plasmid pAD1
(Elsevier, 1991-11)
Enterococcus faecalis cells carrying the conjugative plasmid pAD1 undergo several related changes when induced by the sex pheromone cAD1. Included are the production of novel surface proteins, the formation of cellular ...
Nucleotide Sequence of the 18-kb Conjugative Transposon Tn916 from Enterococcus faecalis
(Elsevier, 1994-11)
Conjugative transposon Tn916 from Enterococcus faecalis DS16 encodes tetracycline resistance (Tet M) as well as determinants necessary for its own movement. Determination of the nucleotide sequence of Tn916 has been ...
Fate and expression of simian virus 40 DNA after introduction into murine cells under nonselective conditions
(Elsevier, 1987-05)
When SV40 infects mouse cells, it does not replicate but instead causes neoplastic transformation of a small percentage of the cells. It is unknown, however, what happens to the virus in those cells that do not become ...
