Isolation and structure of the bacterial sex pheromone, cAD1, that induces plasmid transfer in Streptococcus faecalis
(Elsevier, 1984-12-03)
The Streptococcus faecalis sex pheromone cAD1, which is involved in the conjugative transfer of the hemolysin plasmid pAD1, has been isolated and its structure determined. Its Mr is 818 and its amino acid sequence is ...
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 ...
The nusA recognition site : Alteration in its sequence or position relative to upstream translation interferes with the action of the N antitermination function of phage lambda
(Elsevier, 1984-12-25)
The phage [lambda] transcription antitermination protein, pN, acts with host factors. Nus, at sites on the phage genome, nut, to render RNA polymerase resistant to subsequent downstream termination signals. The NusA protein ...
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.
RNA splicing: Advantages of parallel processing
(Elsevier, 1982-10-21)
Parallel and sequential modes of RNA processing are systematically compared by an analysis of the relevant kinetic reaction schemes. The parallel mode is shown to be superior in the sense that it allows molecules to be ...
Isolation and mapping of Mu nu mutants which grow in him mutants of E. coli
(Elsevier, 1982-07-15)
Mu nuA and Mu nuB mutants were selected by their ability to form plaques on lawns of Escherichia coli himA and himB mutants, respectively. Deletion mapping of the nuA and nuB mutations by marker rescue from [lambda]pMu ...
Introduction to S-systems and the underlying power-law formalism
(Elsevier, 1988)
A novel approach to the development of an appropriate formalism for representing organizationally complex systems began in the mid 1960's with a search for a general systematic formalism that would retain the essential ...
Accuracy of proofreading with zero energy cost
(Elsevier, 1981-11-07)
Accuracy of biological discrimination at the molecular level is known in some systems to involve kinetic proofreading mechanisms. Hopfield and Ninio were the first to propose simple specific kinetic mechanisms for such ...
A critique of the use of DNA synthesis as a measure of the effect of mitogens on lymphocytes
(Kluwer Academic Publishers; The Biochemical Society ; Springer Science+Business Media, 1982-02)
