The Protein Coats or "ghosts" of Coliphage T2
نویسندگان
چکیده
A method of preparing the protein coats or ghosts of phage T2 is described along with proof that the lytic action is a property of the ghost. An assay based on the lytic action toward host cells has been developed which permits a rapid evaluation of the number of ghosts with a reliability of +/-15 per cent. The antigenic and certain physicochemical properties of the ghost have been determined.

Phage coats or ghosts, composed entirely of protein, appear to be responsible for protecting the phage nucleic acid from degradation by factors in the surrounding medium; attachment of the virus to its susceptible host; and delivering the nucleic acid to the interior of the cell. In addition, the ghosts have a number of biological actions which resemble similar actions of the patent phage. Thus...
متن کاملPurification of B. megatherium Phage G and Evidence for a Muralytic Enzyme as an Integral Part of the Phage
The Purification Of B. megatherium G phage is described and it is shown that DEAE cellulose chromatography combined with conventional methods gave a phage preparation which was at least 95 per cent pure, and contained 2.16 microg nitrogen/10(11) infective particles. The phage particle weight in molecular weight units was 91 x 10(6). The small amount of contaminating material appeared to represe...
متن کاملPhotosensitization of T2 coliphage with toluidine blue.
The photodynamic action of dyes upon biological systems has been reviewed by Blum (1941). Inactivation of bacteriophage by this process has been studied by Clifton (1931), Perdrau and Todd (1933), Burnet (1933), Morales (1941), and Pacheco and Morales (1941). More recently, Welsh and Adams (1954) and Yamamoto (1956, 1958) investigated the kinetics of photodynamic inactivation of coliphage. In t...

Duckworth, Donna H. (Johns Hopkins University, Baltimore, Md.), and Maurice J. Bessman. Assay for the killing properties of T2 bacteriophage and their "ghosts." J. Bacteriol. 90:724-728. 1965.-A procedure for the assay of bacteriophage and their "ghosts" which is based on their ability to kill cells is described. The method is derived from the well-known ability of phage and ghosts to prevent t...
متن کاملSite-specific recombination in the cyanobacterium Anabaena sp. strain PCC 7120 catalyzed by the integrase of coliphage HK022.
The integrase (Int) of the lambda-like coliphage HK022 catalyzes the site-specific integration and excision of the phage DNA into and from the chromosome of its host, Escherichia coli. Int recognizes two different pairs of recombining sites attP x attB and attL x attR for integration and excision, respectively. This system was adapted to the cyanobacterium Anabaena sp. strain PCC 7120 as a pote...
