Initiation and termination signals for transcription in bacteriophage M13.

Transcription of the infrequently expressed phage M13 genome domain, comprising genes III, VI, I and IV, has been studied in detail by hybridization and S1-nuclease mapping studies. The contiguous genes III and VI are transcribed via an 1800 nucleotide-long RNA molecule that is initiated at a promoter which overlaps with the Rho-independent termination signal between genes III and VIII. Its syn...

Transcription termination signals in the nin region of bacteriophage lambda: identification of Rho-dependent termination regions.

The approximately 3-kb nin region of bacteriophage lambda, located between genes P and Q contains transcription termination signals as well as 10 open reading frames. Deletions in the nin region frees phage growth from dependence on the lambda-encoded N-transcription antitermination system, conferring a Nin phenotype (N-independence). A subregion of nin, roc, is defined by a 1.9-kb deletion (de...

Expression of bacteriophage M13 DNA in vivo. Localization of the transcription initiation and termination signal of the mRNA coding for the major capsid protein.

During the infection cycle of the filamentous bacteriophage M13 a phage specific RNA species is made which selectively directs in vitro the synthesis of the precursor of the major capsid protein encoded by gene VIII. This RNA is unstable (its mean half-life is 11 min) and is made in amounts representing at least 2% of the newly synthesized RN. Nucleotide sequence analysis have indicated that th...

Initiation and termination mutants of Bacillus subtilis bacteriophage SPO1.

Mutants affected in cistrons 21 and 32 of bacteriophage SPO1 are defective specifically in the initiation of DNA replication. Mutations in cistron 32 also specifically affect the termination of replication.

Translation of chloroplast-encoded mRNA: potential initiation and termination signals.

A survey of 196 protein-coding chloroplast DNA sequences demonstrated the preference for AUG and UAA codons for initiation and termination of translation, respectively. As in prokaryotes at every nucleotide position from -25 to +25 (AUG is +1 to +3) and for 25 nucleotides 5' and 3' to the termination codon an A or U is predominant, except for C at +5 and G at +22. A Shine-Dalgarno (SD) sequence...
