Two subfamilies of murine retrotransposon ETn sequences
(Elsevier, 1990-02-14)
Early transposon (ETn) elements are 5.7-kb retrotransposons found in the murine genome. We have sequenced large portions of two ETn elements that have apparently transposed within the DNA of a murine myeloma cell line, ...
Strategies for representing metabolic pathways within biochemical systems theory: Reversible pathways
(Elsevier, 1989-06)
The search for systematic methods to deal with the integrated behavior of complex biochemical systems has over the past two decades led to the proposal of several theories of biochemical systems. Among the most promising ...
Construction of Enterococcus faecalis pAD1 miniplasmids: Identification of a minimal pheromone response regulatory region and evaluation of a novel pheromone-dependent growth inhibition
(Elsevier, 1989-09)
Several pAD1 miniplasmids were constructed that consisted of all or a portion of the pAD1 EcoRI B fragment with pheromone-inducible "E region" lacZ transcriptional fusions. Miniplasmids containing the entire EcoRI B fragment ...
Efficient and quantitative incorporation of diaminopimelic acid into the peptidoglycan of Salmonella typhimurium
(Elsevier, 1986-09)
Diaminopimelic acid is incorporated into the peptidoglycan of Salmonella typhimurium in an efficient and quantitative manner. The amount of DAP incorporated is similar to the number of molecules estimated to exist in the ...
Cooperative effects of bacterial mutations affecting [lambda] N gene expression : I. Isolation and characterization of a nusB mutant
(Elsevier, 1976-08)
We report the isolation and characterization of an Escherichia coli mutant which limits the growth of phage [lambda] by inhibiting the expression of the N gene regulatory function. The mutation involved maps near minute ...
Recasting nonlinear differential equations as S-systems: a canonical nonlinear form
(Elsevier, 1987-11)
An enormous variety of nonlinear differential equations and functions have been recast exactly in the canonical form called an S-system. This is a system of nonlinear ordinary differential equations, each with the same ...
Plasmid transfer in Streptococcus faecalis: Production of multiple sex pheromones by recipients
(Elsevier, 1979-07)
In a previous report (1978, Proc. Nat. Acad. Sci. USA 75, 3479-3483), we showed that recipient strains of Streptococcus faecalis excrete a heat-stable substance (sex pheromone) which induces donor cells carrying certain ...
Growth of continuous bonelike mineral within porous poly(lactide- co -glycolide) scaffolds in vitro
(John Wiley & Sons, Inc., 2000-04)
Strategies to engineer bone have focused on the use of natural or synthetic degradable materials as scaffolds for cell transplantation or as substrates to guide bone regeneration. The basic requirements of the scaffold ...
A [phi]80 function inhibitory for growth of lambdoid phage in him mutants of Escherichia coli. Deficient in integration host factor II. Physiological analysis of the abortive infection
(Elsevier, 1985-01-30)
Derivatives of phage [lambda] with the rightmost 3% of the genome (the QSR region) from the related phage [phi]80 fail to grow at low temperatures (e.g., 32[deg]) in Escherichia coli. hosts deficient in either protein ...
Equivalence between S-systems and Volterra systems
(Elsevier, 1986-03)
S-systems and Volterra systems have been developed independently of each other in different branches of biology. We show that these systems are mathematically equivalent.
