Growth of [lambda] variants with added or altered promoters in N-limiting bacterial mutants: Evidence that an N recognition site lies in the PR promoter
(Elsevier, 1976-05)
Transcription of the [lambda] genome, initiating at the early rightward promoter (PR), traverses the cII-O-P operon and extends through the Q gene. In the absence of the [lambda] N function, this transcription is prematurely ...
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 ...
[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. ...
The Use of a Rapid Enzymatic Assay in the Field for the Detection of Infections Associated with Adult Periodontitis
(Blackwell Publishing Ltd, 1993-12)
There are few objective assays for studies of the epidemiology of periodontal diseases. The PerioScan™ is an assay capable of detecting three periodontal pathogens, namely T. denticola, P. gingivalis, and B. forsythus, ...
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 ...
