RNA polymerase interaction with dnaB protein and lambda P protein during lambda replication.
The Escherichia coli GroP- phenotype, associated with some dnaB mutants and measured as a decreased ability to plate lambda bacteriophage, was altered by some rpoB mutations. The rpoB effect showed an allele specificity. The participation both of dnaB and of lambda P alleles in the GroP- phenotype was also allele specific. It was concluded that RNA polymerase, dnaB protein, and lambda P protein...
متن کاملProteinase sensitivity of bacteriophage lambda tail proteins gpJ and pH in complexes with the lambda receptor.
Previous studies have shown that bacteriophage lambda initially binds to liposomes bearing its receptor protein by the tip of the tail fiber (type 1 complex). It then associates more directly so that the hollow tail tube is in direct contact with the membrane (type 2 complex). DNA can be injected across the lipid bilayer into the liposome from type 2 complexes. We show here that gpJ, the tail f...
متن کاملNucleotide sequence of the O gene and of the origin of replication in bacteriophage lambda DNA.
The nucleotide sequence of the O gene in bacteriophage lambda DNA is presented. According to two possible initiator codons, the primary structure of the O protein deduced from the DNA sequence consists of 278 or 299 amino acid residues. Structure and function of the O protein--one of the two phage initiator proteins for lambda DNA replication--are discussed in the light of a secondary structure...
متن کاملp-Lambda-bounded variation
A characteriation of continuity of the $p$-$Lambda$-variation function is given and the Helly's selection principle for $Lambda BV^{(p)}$ functions is established. A characterization of the inclusion of Waterman-Shiba classes into classes of functions with given integral modulus of continuity is given. A useful estimate on modulus of variation of functions of class $Lambda BV^{(p)}$ is found.
متن کاملOn the Spaces of $lambda _{r}$-almost Convergent and $lambda _{r}$-almost Bounded Sequences
The aim of the present work is to introduce the concept of $lambda _{r}$-almost convergence of sequences. We define the spaces $fleft( lambda _{r}right) $ and $f_{0}left( lambda _{r}right) $ of $ lambda _{r}$-almost convergent and $lambda _{r}$-almost null sequences. We investigate some inclusion relations concerning those spaces with examples and we determine the $beta $- and $gamma $-duals of...
