Uniform nomenclature for bacterial plasmids: a proposal.

A proposal for a uniform nomenclature in bacterial genetics.

Proposal for a uniform nomenclature for simian virus 40 mutants.

A uniform nomenclature for simian virus 40 mutants has been developed. This nomenclature should evolve into a comprehensive nomenclature as new mutants and information are obtained. Hopefully, his nomenclature will also stimulate the development of a comprehensive nomenclature for all animal virus mutants.

Nomenclature of Transposable Elements in Prokaryotesl

At the Cold Spring Harbor meeting on DNA insertions, a committee was elected to draft a set of rules for nomenclature (Campbell et al., 1977), These rules were based on discussions held at the meeting and on previously accepted conventions for the Mu prophage (Howe and Bade, 1975), for bacterial plasmids (Novick et al., 1976), for bacteriophage A (Hershey, 197 1), and for bacterial genetics (De...

CONSTRUCTION OF RECOMBINANT PLASMIDS FOR PERIPLASMIC EXPRESSION OF HUMAN GROWTH HORMONE IN ESCHERICHIA COLI UNDER T7 AND LAC PROMOTERS

In order to study the periplasmic expression of human growth hormone (hGH) in Escherichia coli, the related cDNA was inserted in two expression plasmids carrying pelB signal peptide, one with lac bacterial promoter and the other with a bacteriophage T7-based promoter. The recombinant plasmids were moved to TG1 and BL21 strains of E. coli, respectively. To induce the expression systems, IPTG and...

Using Mahalanobis distance to compare genomic signatures between bacterial plasmids and chromosomes

Plasmids are ubiquitous mobile elements that serve as a pool of many host beneficial traits such as antibiotic resistance in bacterial communities. To understand the importance of plasmids in horizontal gene transfer, we need to gain insight into the 'evolutionary history' of these plasmids, i.e. the range of hosts in which they have evolved. Since extensive data support the proposal that forei...
